Which of the following is not a correct method of the preparation of benzyl amine from cyano benzene?
  1. H2/Ni
  2. (i) HCl/H2O (ii) NaBH4
  3. (i) SnCl2+HClgas (ii) NaBH4
  4. (i) LiAlH4 (ii) H3O+

Solution

When cyano benzene reacts with hydrochloric acid and water to form benzoic acid which in turn reacts with sodium borohydride to form benzyl alcohol.

Thus benzy lamine is not formed in option (b). Thus using  HCl/H2O and NaBH4 is not a correct method of the preparation of benzyl amine from cyano benzene.
