In order to prepare well, it’s very important to read and revise as much as possible as the majority of topics are theoretical and there are always certain possibilities of forgetting things.
1. Important chapters for JEE Main and Advanced in Physical Chemistry:
a. Mole Concept: It is one of the most basic and very important concepts in physical chemistry and to develop a strong understanding of the entire unit you need to prepare well. Several questions in JEE Exams are asked from this unit but they could be solved easily if you have a firm command over the concepts.
b. Atomic Structure: Every year in JEE Exams, around 2 to 3 questions are generally asked from this unit and this unit does not have any direct correlation with the Mole Concept. The remaining topics like Electrochemistry, Thermodynamics, Equilibrium, Kinetics, etc. are essentially derived from the mole concepts and have nearly equal weightage.
2. Important chapters for JEE Main and Advanced in Inorganic Chemistry:
All the topics included in Inorganic Chemistry are equally important. Therefore, don’t skip any topic from this unit as it is one of the high scoring subjects. Since there are various compounds and you need to study their methods of preparation, uses, chemical reactions, etc. So, it is better to have a proper analysis of all the topics included in JEE Syllabus from Inorganic Chemistry so that while preparing you won’t get diverted from the syllabus.
Several conceptual questions are asked from s, p, d and f-block elements thus, instead of memorizing it’s important to understand it through visualization so that certain complex properties and compositions could be understood easily. You could understand the reactions very easily if you have a good knowledge of periodic table along with the trends in the properties of atoms like atomic radius, electron affinity, electronegativity, ionization and the electrode potential.
3. Organic Chemistry:
The entire portion of organic chemistry could be easily understood if you are well versed with the general topics in organic chemistry that includes nucleophiles, electrophiles, type of reactions, basicity, acidity, etc and the remaining portion of organic chemistry is just its application part. These topics are covered in the GENERAL ORGANIC CHEMISTRY part of the JEE syllabus.
a. Named Reactions: There are several standard named reactions in organic chemistry and you should know all these named reactions along with their mechanisms so that, you could easily solve any similar type of problem asked in the question paper.
b. Organic Synthesis: It is one of the important and conceptual aspect of organic chemistry and every year in JEE Exams, around 2 to 3 questions are asked from this section that includes writing certain steps to synthesize any particular compound by the provided set of reagents with as little efforts as possible. Sometimes, you have to write the missing chemicals in any particular step of the synthesis. Therefore, it is very important to know some of the common chemical reactions.
