- (A)-(II), (B)-(I), (C)-(IV), (D)-(III)
The Correct Option is B
Approach Solution - 1
Step-by-step Explanation:
To solve this problem, we need to match the processes in List-I with their corresponding distillation techniques in List-II based on the properties of the mixtures and the distillation methods suitable for separating them.
- (A) Aniline from aniline-water mixture: Aniline and water have different boiling points. Aniline can be separated from water using steam distillation as it allows the separation of high boiling point components without decomposition. Thus, (A) matches with (IV).
- (B) Glycerol from spent-lye in the soap industry: Glycerol is typically separated from other compounds using distillation at reduced pressure to avoid decomposition at high temperatures. Thus, (B) matches with (III).
- (C) Different fractions of crude oil in the petroleum industry: Crude oil is separated into various fractions using fractional distillation due to the complex mixture of hydrocarbons with different boiling points. Thus, (C) matches with (II).
- (D) Chloroform-Aniline mixture: A simple mixture where components have distinct boiling points can be separated using simple distillation. Thus, (D) matches with (I).
Conclusion:
The correct matching is: (A)-(IV), (B)-(III), (C)-(II), (D)-(I).
Therefore, the correct answer is: (A)-(I), (B)-(II), (C)-(III), (D)-(IV).
Approach Solution -2
To solve the problem, we need to match each item in List-I with the appropriate item in List-II based on appropriate separation techniques used in chemistry.
- Aniline from aniline-water mixture: Aniline and water form a simple mixture where they can be separated by simple distillation due to their difference in boiling points. Therefore, (A) matches with (I).
- Glycerol from spent-lye in soap industry: Glycerol is often recovered from spent-lye by steam distillation. This method allows glycerol to be distilled out while leaving behind any non-volatile impurities. Therefore, (B) matches with (IV).
- Different fractions of crude oil in petroleum industry: Crude oil is separated into its different components based on their boiling points using fractional distillation. Therefore, (C) matches with (II).
- Chloroform-Aniline mixture: A chloroform-aniline mixture is usually separated by distillation at reduced pressure. This helps in preventing decomposition and allows separation based on different boiling points. Therefore, (D) matches with (III).
After analyzing each separation process, the correct answer is:
(A)-(I), (B)-(IV), (C)-(II), (D)-(III)
