Nucleophilic Addition to Carbonyl Compounds
Learn the mechanisms and outcomes of nucleophilic addition reactions to aldehydes and ketones, including cyanohydrin, hydrazone, and Schiff base formation.
Why this shows up in the exam
Mechanisms and product identification are frequently tested.
How NEET tests this
Practise it
These are real questions from past NEET papers that test this exact idea.
Complete the following reaction: Cyclohexanone ([A]) --(HCN)--> Cyclohexanone cyanohydrin ([B]) --(conc. H₂SO₄, Δ)--> [C] [C] is
