Step-by-step solution
(A) Chloroform + Aniline → III Distillation (B) Benzoic acid + Napthalene →   IV Crystallisation (C) Water + Aniline → I Steam distillation (D) Napthalene + Sodium chloride → II Sublimation Aniline is purified using the process of steam distillation because aniline is steam volatile and it is insoluble in water. Chloroform and aniline having boiling points 334   K and 457   K can be separated by distillation. More volatile chloroform vaporizes first and is collected in the rec
