Match List-I with List-II.

| | List-I (Technique) | | List-II (Application) |
|---|---|---|---|
| A | Distillation | I | Separation of glycerol from spent-lye |
| B | Fractional distillation | II | Aniline - Water mixture |
| C | Steam distillation | III | Separation of crude oil fractions |
| D | Distillation under reduced pressure | IV | Chloroform - Aniline |

Choose the correct answer from the options given below:

Canvas Classes · Accepted Answer

Step 1: Criteria for Each Technique

- Distillation (Simple): bp difference  25°C between two components
- Fractional Distillation: bp difference < 25°C or multiple components with overlapping boiling points
- Steam Distillation: compound must be steam-volatile AND water-immiscible
- Distillation under Reduced Pressure: compound decomposes at normal boiling point

Step 2: Analyse Each Application

- Chloroform–Aniline (IV): CHCl₃ bp = 61°C, Aniline bp = 184°C → difference = 123°C → Technique A (
