Options
- AA-I, B-IV, C-II, D-III
- BA-IV, B-I, C-II, D-III
- CA-IV, B-I, C-III, D-II
- DA-I, B-IV, C-III, D-II
Correct answer
B. A-IV, B-I, C-II, D-III
Step-by-step solution
Chloroform (b.p. 334 K) and aniline (b.p. 457 K) have a large difference in their boiling points, so they are separated by simple distillation (A-IV). Fractions of crude oil have close boiling points and are separated by fractional distillation (B-I). Aniline is steam volatile and immiscible with water, so it is separated from an aniline-water mixture by steam distillation (C-II). Glycerol decomposes at its normal boiling point, so it is separated from spent-lye by distillation under reduced pressure (D-III). There
