Important Topics of Hydrogen in JEE Main 2026
The Hydrogen section of the JEE Main 205 Chemistry Syllabus is a fundamental chapter of Inorganic Chemistry and it is important for building foundational knowledge which connects to other topics in Chemistry. The key concepts covered in Hydrogen have been discussed below.
- Hydrogen Bonding - It deals with the impact on boiling/melting points, solubility, and biological systems.
- Position in the Periodic Table - Unique position because of properties resembling both Group 1 (alkali metals) and Group 17 (halogens).
- Water and Heavy Water - It deals with Properties, structure, and significance in chemical reactions.
- Isotopes of Hydrogen - The isotopes of hydrogen are protium, deuterium, and tritium with key differences in abundance, physical, and chemical properties.
- Hydrides - They are of 3 types namely ionic hydrides which are formed with alkali and alkaline earth metals, covalent hydrides which are formed with non-metals and metallic hydrides which are found in d- and f-block elements.
- Industrial and Environmental Applications - Hydrogen as a sustainable clean energy is used in the Haber process, hydrogenation of oils, and fuel cells.
