Step-by-step solution

Nitrobenzene is converted to Aniline using Sn/HCl . This involves the removal of oxygen and addition of hydrogen, which is a Reduction reaction. Aniline reacts with NaNO₂/HCl (which forms HNO₂ in situ) to form Benzene Diazonium Chloride. The process of conversion of a primary aromatic amine into its diazonium salt is called Diazotization. Benzene Diazonium Chloride reacts with another molecule of aniline in a mildly acidic medium to form p -amino Azobenzene. This is an electrophilic aromatic substitution where the
