Column – I(Mixture of compounds)Column – II(Purification Technique)Correct Match is :

(1) Chloroform + Aniline – liquid mixture …difference in their boiling point is  greater than 400C.∴Simple distillation is employed.(2) Ortho-nitrophenol is steam volatile but not para nitro phenol (3)    H2O2 decomposes much below its boiling point. It is purified by distillation under reduced pressure.(4) Both Benzoic acid and Naphthalene undergo sublimation. Benzoic acid is soluble in hot water but not naphthalene.    Separation of the mixture is done by crystallization.
