Question

Match List - I with List - II.

Choose the correct answer from the options given below :

• A. A-II, B-III, C-I, D-IV
• B. A-II, B-IV, C-I, D-III
• C. A-II, B-IV, C-III, D-I
• D. A-IV, B-III, C-II, D-I

Answer 1

The Correct Option is B

To solve this question, we need to match each purification technique in List-I with its appropriate use in List-II. 

1. Simple Distillation (A): Simple distillation is used to separate liquids with a large difference in boiling points (usually greater than 25°C). Thus, it matches with \(II\).
2. Fractional Distillation (B): This technique is used specifically when the boiling points of the two liquids are close to each other. This matches with \(IV\).
3. Steam Distillation (C): This method is ideal for separating compounds that are steam volatile and have very high boiling points. Therefore, it pairs with \(I\).
4. Distillation under Reduced Pressure (D): This is used to distill liquids that decompose at their boiling points at atmospheric pressure. It matches with \(III\).

From the analysis above, the correct matching is:

A-II, B-IV, C-I, D-III

Therefore, the correct answer is A-II, B-IV, C-I, D-III.

This methodical approach allows distinguishing each distillation technique's unique application based on the physical properties of the liquids involved.
