Solution
The correct option is A Alanine
Treatment with bromine & a catalytic amount of phosphorus leads to the selective α−bromination of carboxylic acids.3/2Br2+P⟶PBr3CH3CH2CO2H+PBr3⟶3CH3CH2COBr+H3PO3 O OCH3−CH2−||C−Br⇌CH3−CH|−||C−OH tautomerism Br O OCH3−CH|−||C−OHalcNH3−−−−→CH3−CH|−||C−OH Br NH2Alanine
