Chloroform (b.p. ) is mixed with aniline (b.p. ). The simplest adequate method of separating the two liquids is

  1. Afractional crystallisation
  2. Bsimple distillation
  3. Csublimation
  4. Dpaper chromatography on a preparative scale

Answer: B

The boiling points differ by 123 K, which is large, so a single simple distillation collects chloroform first and leaves aniline. A fractionating column is not needed.
