An organic compound (A) C_(6)H_(6)O gives violet colour with neutral FeCl_(3) solution. With NH_(3) in the presence of anhydrous ZnCl_(3) (A) gives (B) (C_(6)H_(7)N). (A) with dimethyl sulphate gives ( C) (C_(7)H_(8)O). What are (A), (B) and (C )? Explain the reactions. |

Answer» Solution :(i) An organic compound (A) `C_(6)H_(6)O` gives violet colour with netural `FeCl_(3)` solution. (ii) With `NH_(3)` in the presence of anhydrous `ZnCl_(2)` (A) gives (B) `(C_(6)H_(7)N)`. `C_(6)H_(5)OH + NH_(3) overset(ZnCl_(2)//473 K) to C_(6)H_(5)NH_(2) + H_(2)O` (iii) (A) with DIMETHYL sulphate gives (C ) `(C_(7)H_(8)O)`. `C_(6)H_(5)OH + underset("dimethyl sulphate")(CH_(3))_(2)SO_(4) overset(NAOH) to C_(6)H_(5)OH + underset("Methyl hydrogen sulphate")(CH_(3)OSO_(2)OH)`
