Explanation:
This problem requires matching processes in List-I with their corresponding distillation techniques in List-II. The matching is based on the properties of the mixtures and the suitability of distillation methods for their separation.
- (A) Aniline from Aniline-Water Mixture: Aniline and water exhibit different boiling points. Steam distillation is employed to separate aniline from water, enabling the isolation of high-boiling point components without thermal decomposition. Consequently, (A) aligns with (IV).
- (B) Glycerol from Spent-Lye (Soap Industry): Glycerol is typically separated from other constituents via distillation under reduced pressure to prevent decomposition at elevated temperatures. Thus, (B) corresponds to (III).
- (C) Different Fractions of Crude Oil (Petroleum Industry): Crude oil, a complex mixture of hydrocarbons with varying boiling points, is separated into distinct fractions through fractional distillation. Therefore, (C) matches with (II).
- (D) Chloroform-Aniline Mixture: For simple mixtures with clearly differentiated boiling points, simple distillation is the appropriate separation method. Hence, (D) aligns with (I).
Result:
The correct pairings are: (A)-(IV), (B)-(III), (C)-(II), (D)-(I).
The correct answer is: (A)-(IV), (B)-(III), (C)-(II), (D)-(I).
