Chemistry is the most scoring section in IIT-JEE. It is also a homogeneous paper that does not take you through strange allays.
A question will appear from each chapter of Chemistry. The weight age is tilted slightly more towards Physical and Organic Chemistry.
In Physical Chemistry Chemical Thermodynamics and Thermochemistry, Electrochemistry, Ionic Equilibrium, Chemical Kinetics, States of matter are important. You can easily score good marks in Chemistry by doing these topics well.
These topics are very important in Organic Chemistry - The topics which involve reactions of alkynes, alekenes, alcohols and carbonyl compounds. Carbonyl compounds are of prime concern. Pay proper attention to organic acids and bases and Bio-molecules.
In Inorganic Chemistry periodic properties, chemical bonding and extraction of metals, qualitative analysis and coordination compound (including crystal field theory) are important. Also pay attention to s, p, and d block elements.
