JEE Main 2026 Apr 5 Shift 2, Chemistry Q12: Purification Methods
JEE Main2026Apr 5, Shift 2Chemistry
Q.
Match List-I with List-II.
| List-I (Purification technique) | List-II (Used to separate) |
|---|---|
| A. Simple distillation | I. Steam volatile compound |
| B. Fractional distillation | II. Two liquids with large difference in boiling points |
| C. Steam distillation | III. Liquid decomposing at its boiling point |
| D. Distillation under reduced pressure | IV. Two liquids with close boiling points |
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
Solution
Standard mapping:
Simple distillation separates two liquids with widely different boiling points (II).
Fractional distillation separates two liquids with close boiling points using a fractionating column (IV).
Steam distillation used for steam-volatile compounds (I).
Distillation under reduced pressure used for liquids that decompose at their normal boiling point (III).
This gives A-II, B-IV, C-I, D-III, which is option (2).
