MolSynapse / Question bank / Organic Reaction Mechanisms I: Nucleophiles and Carbonyl Addition / Nucleophilic addition to aldehydes and ketones

JEE Main levelSingle correct optionDifficulty 2 of 3o1084

4-Nitrobenzaldehyde is treated with $NaBH X_{4}$ in ethanol, then dilute acid. The product is

A4-nitrobenzoic acid
B4-aminobenzaldehyde
C(4-aminophenyl)methanol
D(4-nitrophenyl)methanol

Answer: D

NaBH X_{4}

reduces aldehydes and ketones selectively and leaves a nitro group on the ring untouched. The aldehyde becomes

- CH X_{2} OH

.
