Answer»

Solution :(a) Coupling reaction :

(B) Hoffmann.s bromamide reaction :
`underset("ETHANAMIDE")(CH_(3)-overset(overset(O)(||))(C)-NH_(2))+Br_(2)+4KOH rarr underset("Methanamine")(CH_(3)NH_(2))+K_(2)CO_(3)+2KBr+2H_(2)O`
(c) Acetylation :
When ANILINE reacts with acetyl chloride in the presence of NaOH, we get acetanilide. This process is called acetylation.
