Aldehydes undergo:
Correct answer: C. Nucleophilic addition reaction
- A. Electrophilic addition reaction
- B. Substitution reaction
- C. Nucleophilic addition reaction
- D. None of these
Explanation
So, when aldehydes undergo nucleophilic addition reactions, it means that a nucleophile (a species with a lone pair of electrons) attacks the carbonyl carbon of the aldehyde. This results in the formation of a new bond between the nucleophile and the carbon, while the oxygen atom of the carbonyl group gets a new bond with a hydrogen atom.

About Nucleophilic Addition Reactions
Nucleophilic addition occurs at the polar carbonyl group of aldehydes and ketones, where a nucleophile attacks the electron-deficient carbon atom. Reactions with hydrogen cyanide, sodium bisulfite, alcohols and Grignard reagents are explained through tetrahedral intermediates, acid or base catalysis, and the different reactivity of aldehydes and ketones.
