An aromatic compo

Answer :

It is given that compound 'C' having the molecular formula,C6H7N is formed by heating compound 'B' with Br2and KOH. This is a Hoffmann bromamide degradation reaction(in which isicyanide compound is formed). Therefore, compound 'B' is an amide and compound 'C' is an amine. The only amine having the molecular formula,C6H7N is aniline, .

Therefore, compound 'B' (from which 'C' is formed) must be benzamide, .

Further, benzamide is formed by heating compound 'A' with aqueous ammonia. Therefore, compound 'A' must be benzoic acid.The given reactions can be explained with the help of the following equations:
