Part 2 introduces organic chemistry from scratch, covering classification and nomenclature of organic compounds, purification techniques, and then moving through hydrocarbons, environmental chemistry, and the chemistry of organic compounds containing halogens, oxygen, and nitrogen. The gradual progression from basic IUPAC naming to reaction mechanisms is carefully structured for beginners.

JEE places heavy emphasis on the organic chemistry started in this book — reaction mechanisms, named reactions, and isomerism form the backbone of advanced-level questions. Read each reaction mechanism step by step, draw electron-pushing arrows yourself, and maintain a separate notebook for name reactions and their conditions. This is the same book you will refer back to even in Class 12 for revision of fundamentals.
