Carbonyl & Enolate Chemistry
Exam-focused revision notes on Carbonyl & Enolate Chemistry for CSIR-NET Chemical Sciences, GATE Chemistry and IIT-JAM — the core concepts, the formulas worth memorising, the traps that cost marks, and a quick-recall table.
The carbonyl group — why it reacts
The C=O bond is polarised: carbon is electrophilic (δ+), oxygen nucleophilic (δ−). Two themes dominate the whole topic — nucleophilic addition at the carbonyl carbon, and enolate chemistry at the α-carbon.
