JEE Main 2026 — 5 April, Evening Shift — Question 59
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. Vacuum distillation (under reduced pressure) | IV. Two liquids with close boiling points |
Choose the correct answer from the options given below :
- Option A:
A-II, B-III, C-I, D-IV
- Option B:Correct
A-II, B-IV, C-I, D-III
- Option C:
A-II, B-IV, C-III, D-I
- Option D:
A-IV, B-III, C-II, D-I
Answer: B
Step-by-step solution
Simple distillation separates liquids with large boiling point differences (A-II). Fractional distillation separates liquids with close boiling points (B-IV). Steam distillation is used for steam volatile compounds (C-I). Vacuum distillation is used for liquids that decompose at their boiling point (D-III). Hence B-II, B-IV, C-I, D-III is correct.
