JEE Main 2021 (31 Aug, Shift 2) Chemistry Q47: Amines

Question

The major products A and B formed in the following reaction sequence are :
[benzene ring (inner circle) bearing $\mathrm{NH_2}$; acetic anhydride drawn above the arrow] -> A -> ($\mathrm{Br_2}$, $\mathrm{CH_3COOH}$, Room Temperature) B

Accepted Answer

Option 1: A = benzene ring bearing NH-C(=O)-CH3 (NH, then C with =O and CH3), B = same ring bearing NH-C(=O)-CH3 with Br at the position opposite (para) to it

Answer

A = benzene ring bearing NH-C(=O)-CH3 (NH, then C with =O and CH3), B = same ring bearing NH-C(=O)-CH3 with Br at the position opposite (para) to it

Answer

A = benzene ring bearing NH2 at top and COCH3 at bottom (para), B = ring bearing NH2 at top, Br on the carbon adjacent to the NH2 carbon, and COCH3 at bottom

Answer

A = benzene ring bearing NH-C(=O)-CH3, B = same ring bearing NH-C(=O)-CH3 with Br at a meta position as drawn (lower right)

Answer

A = benzene ring bearing NH2 at top and COCH3 at bottom (para), B = ring bearing NH2 at top, Br on both carbons adjacent to the NH2 carbon, and COCH3 at bottom
