Many students find organic chemistry a challenging part of the chemistry section. However, it is necessary to build a solid foundation of this topic, as a lot of questions are asked from organic chemistry. The JEE Main Basics of Organic Chemistry Practice Questions with Solutions have a variety of questions from this topic for students to practice and strengthen their chemistry section for the JEE Main entrance test.
About 2 to 3 questions may appear from the basics of organic chemistry practice questions on the JEE Main question paper. Usually, the question will be in the form of multiple choice questions and integer-type questions, testing the student’s proficiency in organic chemistry. The JEE Main exam is a highly competitive entrance exam for all engineering aspirants. Therefore, it is essential for candidates to attempt these practice tests at least once a week to develop knowledge of the topic and answer questions with precision.
The important topics of the Aldehydes, Ketones and Carboxylic Acids chapter, from which questions may appear, are Fundamental Concepts of Organic Chemistry, Nomenclature, Isomerism, Acidity & Basicity, and Reaction Mechanisms and Types. The practice tests, containing questions on all these topics along with their detailed solutions, will allow aspirants to understand the basic concepts well by going through the detailed explanations provided.
Attempting the JEE Main Basics of Organic Chemistry Practice Questions with Solutions on a regular basis will improve the accuracy of the student and help them manage their time better during the main examination. Thorough practice will also allow them to understand their weak areas, work on them, and gain confidence in solving questions from this topic with ease in the JEE Main exam.
