Benzamide (C_6H_5CONH_2) on heating with bromine and NaOH gave a compound A which is soluble in dilute acid. When A is warmed with chloroform and alc KOH, B is formed which has an unpleasant odour. What is reaction called as?

Benzamide (C_6H_5CONH_2) on heating with bromine and NaOH gave a compound A which is soluble in dilute acid. When A is warmed with chloroform and alc KOH, B is formed which has an unpleasant odour. Using chemical equation represent the formation of B from A.

Compounds A and B are isomers with formula C_2 H_4 Cl_2 . On treatment with aq. KOH, A gives a compound C which liberates ' H_2' gas on treatment with Na metal, B on treatment with aq.NaOH produces D which answers iodoform test. Give the structures of A,B,C and D and write the chemistry of reactions.
