Acetanilide (CX6HX5NHCOCHX3) is nitrated with HNOX3 in HX2SOX4 at low temperature. The major product is
A4-nitroacetanilide (N-(4-nitrophenyl)ethanamide)
B2,4,6-trinitroacetanilide
C3-nitroacetanilide
Dnitrobenzene
Answer: A
The −NHCOCHX3 group is an activating o/p director, since the nitrogen lone pair is still partly delocalised into the ring. The para isomer is the major product because the ortho positions are hindered by the bulky amide group.
