Purification & Characterisation · Distillation methods
Match List-I with List-II.
Choose the correct answer from the options given below :
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 |
- (1)A-II, B-III, C-I, D-IV
- (2)A-II, B-IV, C-I, D-III
- (3)A-II, B-IV, C-III, D-I
- (4)A-IV, B-III, C-II, D-I
We corrected a printing error in the original paper
Answer corrected; the source key is (3) — steam distillation separates steam-volatile compounds (C-I) and distillation under reduced pressure is used for liquids that decompose at their boiling point (D-III).
