Class 12 Chemistry Part 1 focuses on solutions, electrochemistry, chemical kinetics, surface chemistry, and the d-and f-block elements. These are the most numerically intensive chapters in the NCERT Chemistry series, making them critical for JEE Main where formula-based questions are common.

Electrochemistry and chemical kinetics are particularly important because they combine conceptual understanding with quantitative problem-solving — a combination JEE Advanced often exploits. Work through the NCERT solved examples multiple times until the derivations become second nature. The d-block chapter is a memorisation-heavy area where NCERT's tables of properties and reactions are your best revision tool. Pair your reading with periodic self-tests to stay sharp.
