4-Nitroacetophenone is treated with NaBHX4 in methanol at room temperature. The major product is
A1-ethyl-4-nitrobenzene
B4-aminoacetophenone
C1-(4-aminophenyl)ethanol
D1-(4-nitrophenyl)ethanol
Answer: D
NaBHX4 in methanol is a mild hydride donor that reduces aldehydes and ketones but leaves aromatic NOX2 untouched. Only the ketone is reduced, giving the secondary alcohol 1-(4-nitrophenyl)ethanol.
