Benzamide (A) is prepared by heating benzoic acid with ammonia. It undergoes the following reactions:
`A underset("reaction 1")overset(Br_(2),KOH, Delta)(to) B underset(273-278K "reaction 2")overset(NaNO_(2),HCl)(to) C underset(Delta "reaction 3")overset(H_(3)PO_(2),H_(2)O)(to) D underset(anhyd AlCl_(3) "reaction 4")overset(CH_(3)Cl)(to) E`
E on heating with acidic `KMnO_(4)` gives back benzoic acid.
5. Give reaction for the conversion of E into benzyl alcohol.
