Step-by-step solution
Chloroform (b.p 334 K) and aniline (b.p. 457 K) are easily separated by the technique of distillation. One of the technological applications of fractional distillation is to separate different fractions of crude oil in the petroleum industry. Aniline is separated by steam distillation technique from aniline – water mixture. When an organic compound is present in an aqueous medium, it is separated by shaking it with an organic solvent in which it is more soluble than in water. Hence, correct matching is given
