Compound A (C_(6)H_(6)O) gives violet colouration with neutral FeCl_(3) with CO at 400 K/4 to 7 atm followed by acidification with HCl gives B (C_(7)H_(6)O). Also, gives violet colouration with neutral FeCl_(3) and gives effervescence with NaHCO_(3) solution. Compound A reacts with NH_(3) at 473 K in the presence of anhydrous ZnCl_(2) to give compound C (C_(6)H_(7)N) which undergoes carbylamine test. Identify A, B, C and explain the reactions.

Compound A (C_(6)H_(6)O) gives violet colouration with neutral FeCl_(3

1.	Compound A (C_(6)H_(6)O) gives violet colouration with neutral FeCl_(3) with CO at 400 K/4 to 7 atm followed by acidification with HCl gives B (C_(7)H_(6)O). Also, gives violet colouration with neutral FeCl_(3) and gives effervescence with NaHCO_(3) solution. Compound A reacts with NH_(3) at 473 K in the presence of anhydrous ZnCl_(2) to give compound C (C_(6)H_(7)N) which undergoes carbylamine test. Identify A, B, C and explain the reactions.
Answer» Solution :(i) Compound A `(C_(6)H_(6)O)` gives violet COLOURATION with neutral `FeCl_(3)` with `CO_(2)` at 400 K/ 4 to 7 ATM followed by acidification with HCl gives B `(C_(7)H_(6)O_(3))`. (ii) Compound A reacts with `NH_(3)` at 473 K in the PRESENCE of anhydrous `ZnCl_(2)` to give compound C `(C_(6)H_(7)N)` which undergoes carbylamine test. `underset((A)) (C_(6)H_(5)OH) + NH_(3) overset(ZnCl_(2)//473 K) to underset((C))(C_(6)H_(5)NH_(2)) + H_(2)O`
