Aldehydes and ketones undergo ______?

Aldehydes and ketones are carbonyl compounds that contain the carbonyl group (C=O). This group is highly electrophilic, making it susceptible to nucleophilic attack. Key Reaction Type: The carbon in the C=O bond is partially positive → attracts nucleophiles The double bond breaks, and a new compound forms → nucleophilic addition 🔹 Examples of nucleophilic addition reactions: Addition of HCN → forms cyanohydrins Addition of alcohols → forms hemiacetals and acetals Hydration → forms gem-diols Reduction (e.g., with NaBH₄) → forms alcohols
