How do you convert the following:
(i) C₆H₅CONH₂ to C₆H₅NH₂

(ii) Aniline to phenol

(iii) Ethanenitrile to ethanamine

i) To convert Benzamide to aniline:

Benzamide on heating with a mixture of Br₂ in presence of NaOH or KOH (i.e. NaOBr or KOBr) is given aniline.

ii) Aniline first converts to diazonium salt using NaNO2/HCl at 0-5 degree C, Then diazonium ion reacts with the water at 100 degrees C to produced phenol

(iii)
