Q.51) >Match List I with List II
List I (Mixture) | List II (Method of Separation) | |
---|---|---|
A. CHCl + CHNH | I. Distillation under reduced pressure | |
B. Crude oil in petroleum industry | II. Steam distillation | |
C. Glycerol from spent-lye | III. Fractional distillation | |
D. Aniline + water | IV. Simple distillation |
A) A – II, B – IV, C – I, D – III
B) A – IV, B – III, C – II, D – I
C) A – IV, B – III, C – I, D – II
D) A – III, B – IV, C – I, D – II
A. CHCl? + C?H?NH? (aniline)
These are immiscible liquids, separated using steam distillation
→ Match: II
B. Crude oil in petroleum industry
Crude oil is a complex mixture of hydrocarbons separated by fractional distillation
→ Match: III
C. Glycerol from spent lye (soap industry)
Glycerol is separated using distillation under reduced pressure because it's temperature-sensitive
→ Match: I
D. Alcohol + Water (miscible liquids with different boiling points)
These are separated by simple distillation
→ Match: IV
hence the correct option is (4) A – II, B – III, C – I, D – IV
