Chemical Kinetics:This chapter is both scoring and significant. As it has the foundation for two other chapters - chemical equilibrium and electrochemistry.
General Organic Chemistry: This chapter is scoring because it is simple and contains a lot of JEE questions.
Benzene Reactions: Another important and high-scoring chapter, particularly for JEE Advanced.
Ores and Metallurgy: This chapter is theoretical and is frequently questioned in JEE.
Qualitative analysis: Chapter like this requires a lot of memorization. However the questions asked are direct questions and easy to solve.
