How will you separate a solution (miscible) of benzene + CHCl₃

Options

(a) Sublimation
(b) Filtration
(c) distilation
(d) Crystallisation

Correct Answer:

distilation

Explanation:

Distillation particularly fractional distillation because the boiling point of benzene (80°C) and chloroform (61.5°C) are close. Fractional distillation involves repeated distillation and condensations, in a fractionating column. As a result of distillation and condensation at each point of the fractionating column, the vapours rising up become richer in more volatile component and the liquid falling back into the flask becomes richer in less volatile component. Thus, the low boiling liquid distills first while the higher boilling liquid distills afterwards.
