Benzoic acid on treatment with `Br_2` and `FeBr_3` gives the compound (A), which on tratment with `NH_3` gives the compound(B). The compound (B) on heating gives the compound (C ). Write the structures of compounds (A), (B) and (C ) in the above sequence of reactions.

A neutral liquid A on treatment with Lucas reagent produces a compound B, which upon treatment with alcoholic KOH yields a compound C. The compound C decolourises bromine water and upon ozonolysis forms only methanal. Deduce the structures of A, B and C and explain the reactions.

Which compound does not give NH_3 on heating ?

An aromatic compound A on treatment with aqueous ammonia and heating forms compound B which on heating with Br_(2) and KOH forms a compound C of molecular formula C_(6)H_(7)N . Write the structures and IUPAC names of compounds A, B and C.
