Choose the correct answer from the options given below:
| List-I(Mixture) | List-II(Purification Process) |
| (A) Chloroform & Aniline | (I) Steam distillation |
| (B) Benzoic acid & Napthalene | (II) Sublimation |
| (C) Water & Aniline | (III) Distillation |
| (D) Napthalene & Sodium chloride | (IV) Crystallisation |
- (A)-(IV), (B)-(III), (C)-(I), (D)-(II)
- (A)-(III), (B)-(I), (C)-(IV), (D)-(II)
- (A)-(III), (B)-(IV), (C)-(II), (D)-(I)
- (A)-(III), (B)-(IV), (C)-(I), (D)-(II)
The Correct Option is D
Solution and Explanation
The correct answer is (D):
The correct match is
(A) Chloroform & Aniline → (III) Simple distillation
(B) Benzoic acid & Napthalene → (IV) Crystallisation (Sublimation is not used as both sublime heating)
(C) Water & Aniline → (I) Steam distillation
(D) Napthalene & Sodium chloride → (II) Sublimation (only naphthalene has the tendency for sublimation)

Concepts Used:
Organic Chemistry - Some Basic Principles and Techniques
Organic Chemistry is a subset of chemistry dealing with compounds of carbon. Therefore, we can say that Organic chemistry is the chemistry of carbon compounds and is 200-225 years old. Carbon forms bond with itself to form long chains of hydrocarbons, e.g.CH4, methane and CH3-CH3 ethane. Carbon has the ability to form carbon-carbon bonds quite elaborately. Polymers like polyethylene is a linear chain where hundreds of CH2 are linked together.
