10 00 PM IST - 08 Mar'26

Explain about the Denaturation of Proteins.

When a protein is subjected to physical changes (heat) or chemical changes, the hydrogen bonds are disturbed. The protein loses its secondary and tertiary structures (uncoils), losing its biological activity. A classic example is the coagulation of egg white upon boiling.

09 40 PM IST - 08 Mar'26

What is Zwitterion?

In aqueous solution, the carboxyl group of an amino acid loses a proton and the amino group gains one, creating a dipolar ion called a Zwitterion. It is electrically neutral but carries both positive and negative charges, explaining the high melting points of amino acids.

09 20 PM IST - 08 Mar'26

Differentiate between Physisorption vs. Chemisorption.

Physisorption involves weak Van der Waals forces, is reversible, and forms multilayers. Chemisorption involves strong chemical bonds, is irreversible, highly specific, and forms only a single layer (unilayer). Chemisorption usually requires a specific activation energy to occur.

09 00 PM IST - 08 Mar'26

When does the Frenkel Defect happen?

This occurs when an ion (usually the smaller cation) is displaced from its lattice site to an interstitial position. Since no ions leave the crystal, the density remains unchanged.

08 40 PM IST - 08 Mar'26

What is Schottky Defect?

This stoichiometric defect arises when an equal number of cations and anions are missing from the crystal lattice. It is commonly found in highly ionic compounds where the cation and anion are of similar size. This defect decreases the overall density of the crystal.

08 20 PM IST - 08 Mar'26

What is Werner's Theory (Postulates)?

Every coordination compound exhibits two types of valencies: Primary (ionizable, corresponds to oxidation state) and Secondary (non-ionizable, corresponds to coordination number). Secondary valencies are directional and determine the geometry of the complex, such as octahedral or tetrahedral shapes.

08 00 PM IST - 08 Mar'26

What is Lanthanoid Contraction?

As the atomic number increases in the 4f series, there is a steady decrease in atomic/ionic radii. This is caused by the poor shielding effect of 4f electrons, which allows the nuclear charge to pull the outer electrons more strongly toward the nucleus.

07 40 PM IST - 08 Mar'26

What are the Interhalogen Compounds?

These are formed when two different halogens react. The central atom is always the larger, less electronegative halogen. They are generally more reactive than pure halogens because the X - X́ bond is weaker than the X - X bond.

07 00 PM IST - 08 Mar'26

What is Mond’s Process for Nickel?

Nickel is refined by heating it with Carbon Monoxide to form a volatile complex, Nickel Tetracarbonyl. This complex is then heated to a higher temperature where it decomposes to give 99.9% pure Nickel.

06 40 PM IST - 08 Mar'26

What is the Froth Flotation Process?

This method concentrates sulfide ores like Galena (PbS). The ore is mixed with water and pine oil (collector). Air is blown through the mixture, creating a foam. The ore particles, being wetted by oil, rise to the surface with the froth, while impurities (gangue) sink to the bottom.

06 20 PM IST - 08 Mar'26

Give the chemical evidence to prove that Glucose has a straight chain of six carbon atoms.

When Glucose is heated with Hydriodic acid and red phosphorus for a prolonged period, it undergoes complete reduction to form n-hexane. This reaction confirms that all six carbon atoms in the glucose molecule are linked in a continuous, unbranched straight chain.

06 00 PM IST - 08 Mar'26

Draw the structures of Orthophosphoric acid and Pyrophosphoric acid.

Orthophosphoric acid features a central Phosphorus atom bonded to one oxygen via a double bond and three hydroxyl, making it tribasic. Pyrophosphoric acid is formed by heating orthophosphoric acid, resulting in a P-O-P linkage between two PO₄ units. It contains four ionizable -OH groups, making it tetrabasic.

05 45 PM IST - 08 Mar'26

State Kohlrausch’s law of independent migration of ions.

Kohlrausch’s law states that at infinite dilution, each ion of an electrolyte makes a definite contribution toward the total molar conductivity, regardless of the nature of the other ion. It is widely used to calculate the molar conductivity of weak electrolytes (like acetic acid) at infinite dilution, which cannot be determined directly by extrapolation.

05 30 PM IST - 08 Mar'26

Describe the Cannizzaro reaction.

Aldehydes that do not have any ɑ-hydrogen atoms (like Formaldehyde or Benzaldehyde) undergo self-oxidation and reduction (disproportionation) when treated with concentrated alkali. One molecule is reduced to an alcohol, while the other is oxidized to a carboxylic acid salt.

05 15 PM IST - 08 Mar'26

Explain the Frenkel defect and why it doesn't change the density of a crystal.

A Frenkel defect occurs when an ion leaves its normal lattice site and occupies an interstitial position. Since no ions are actually lost from the crystal, the overall mass and volume remain constant; therefore, the density remains unchanged. This defect is common in compounds with large size differences between ions, like AgCL.

05 00 PM IST - 08 Mar'26

What is Gabriel Phthalimide Synthesis?

This method is used to prepare pure primary aliphatic amines. Phthalimide is treated with KOH, followed by an alkyl halide and subsequent hydrolysis.

04 45 PM IST - 08 Mar'26

What is denaturation of proteins?

Denaturation is the process where a protein loses its native three-dimensional structure (secondary, tertiary, and quaternary) due to physical or chemical stress, such as change in temperature or pH. The primary structure (amino acid sequence) remains intact, but the protein loses its biological activity.

04 30 PM IST - 08 Mar'26

Define the "Inert Pair Effect" with respect to Group 13 or 14 elements.

The inert pair effect is the reluctance of the outermost s - orbital electrons to participate in bond formation due to poor shielding by intervening d and f electrons. This results in heavier elements of groups 13, 14, and 15 exhibiting oxidation states two units lower than the group valence.

04 15 PM IST - 08 Mar'26

How is the Lucas test used to distinguish between primary, secondary, and tertiary alcohols?

The Lucas reagent reacts with alcohols to form alkyl chlorides. Tertiary alcohols react immediately, producing cloudiness (turbidity) instantly. Secondary alcohols produce turbidity within 5–10 minutes. Primary alcohols do not produce turbidity at room temperature but may do so only upon heating. This test identifies alcohols based on their reactivity.

04 00 PM IST - 08 Mar'26

State the Arrhenius equation and explain the terms involved

The Arrhenius equation shows the effect of temperature on the rate constant (k) of a reaction:

K = Ae^-Eɑ/RT

Where A is the frequency factor (pre-exponential factor), Eɑ is the activation energy, R is the gas constant, and T is the absolute temperature. This equation demonstrates that as temperature increases or activation energy decreases, the rate constant K increases exponentially.

Explain the Aldol condensation reaction of Acetaldehyde with the required conditions.

Aldehydes or ketones having at least one ɑ-hydrogen react in the presence of a dilute base to form Β-hydroxy aldehydes. Two molecules of acetaldehyde react to form 3-hydroxybutanal. Upon heating, this product undergoes dehydration to form an ɑΒ-unsaturated aldehyde called Crotonaldehyde.

01 00 PM IST - 08 Mar'26

Define the Nernst equation and state its significance in determining cell potential.

12 45 PM IST - 08 Mar'26

Describe the Mond’s process for refining Nickel with chemical equations.

• Mond’s process is used to refine nickel. Impure nickel is heated with Carbon Monoxide at 350 K to form volatile Nickel Tetracarbonyl, leaving impurities behind.
• The volatile complex is then heated to a higher temperature (450 K), where it decomposes to yield pure Nickel and gas.

12 30 PM IST - 08 Mar'26

Differentiate between Physisorption and Chemisorption based on enthalpy and specificity.

• Physisorption (Physical adsorption) is caused by weak van der Waals forces, has low enthalpy of adsorption (20–40 kJ/mol), and is non-specific.
• Chemisorption (Chemical adsorption) involves strong chemical bonds, has high enthalpy (80–240 kJ/mol), and is highly specific.
• While physisorption decreases with temperature, chemisorption first increases (due to activation energy) and then decreases.

12 15 PM IST - 08 Mar'26

Explain the Schottky defect and its effect on density.

The Schottky defect occurs when an equal number of cations and anions are missing from the crystal lattice. This maintains electrical neutrality but creates vacancies. It is common in highly ionic compounds with high coordination numbers where cations and anions are similar in size. Because atoms are missing from the lattice, the density of the crystal significantly decreases.

12 00 PM IST - 08 Mar'26

Differentiate between the rate of a reaction and the rate constant of a reaction.

The rate of reaction is the speed at which reactants are converted into products, usually expressed as the change in concentration per unit time. In contrast, the rate constant is the proportionality constant in the rate law equation. While the reaction rate depends on the initial concentration of reactants, the rate constant is independent of concentration but changes with temperature.

11 45 AM IST - 08 Mar'26

State the main postulates of Werner’s theory of coordination compounds.

Alfred Werner proposed that metals that are in coordination compounds exhibit two types of valencies: Primary and Secondary. Primary valency is ionizable, corresponds to the oxidation state, and is satisfied by negative ions. Secondary valency is non-ionizable, corresponds to the coordination number, and is satisfied by neutral molecules or negative ions. Secondary valencies have fixed spatial arrangements, determining the geometry of the complex.

11 30 AM IST - 08 Mar'26

What is lanthanide contraction and mention its significant effects?

Lanthanide contraction is the steady decrease in the atomic and ionic radii of lanthanide elements with increasing atomic number. This occurs because the 4f electrons provide poor shielding, allowing the increasing nuclear charge to pull the outer electrons closer.

11 15 AM IST - 08 Mar'26

Describe the structure of diborane and the types of bonds present.

Diborane contains two types of bonds: four terminal B-H bonds and two bridging B-H-B bonds. The terminal bonds are standard two-center, two-electron (2c-2e) bonds. The two bridging hydrogen atoms are held by three-center, two-electron (3c-2e) bonds, often called "banana bonds." Each boron atom is sp₃ hybridized, and the two bridge hydrogens lie in a plane perpendicular to the terminal atoms.

11 00 AM IST - 08 Mar'26

Explain the principle and process of zone refining.

Zone refining is basically based on the principle that states that impurities are more soluble in the molten state in relation to the solid state of the metal. A circular mobile heater melts a narrow zone of an impure metal rod. As the heater moves, the pure metal crystallizes behind it, while impurities concentrate in the adjacent molten zone.
