1.	An aromatic compound (A) of molecular formula C_6H_5Cl on reaction with aqueous NaOH gives (B) of formula C_6H_6Othat give violet colouration with neutral FeCl_3.(B) on reaction with ammonia in presence of anhydrous ZnCl_2gives (C) of formula C_6H_7N. ldentify A, B. C and explain the reactions.
Answer» SOLUTION :(i)An aromatic compound (A) of molecular formula `C_6H_5Cl`is identified as chloro benzenc. (ii) Chloro benzene on reaction with aqueous NaOH produces phenol as (B). `UNDERSET("Chloro benzene(A)")(C_6H_5Cl) + NaOH underset(633K)oveset(300" bar")to underset("Phenol(B)")(C_6H_5OH) + NaCl` (III) Phenol givesaiolet colour with NEUTRAL `FeCl_3`.Phenol on treated with `NH_3` in the presence of anhydrous `ZnCl_2` gives Amline as (C) `underset("Phenol(B)")(C_6H_5OH)+ NH_3 underset(ZnCl_2)overset("anhydrous")to underset("ANILINE(C)")(C_6H_5-NH_2) + H_2O`
