The most suitable method of the separation of a 1:1 mixture of ortho-and para-nitrophenols is

Options

(a) filtration
(b) sublimation
(c) crystallisation
(d) steam distillation

Correct Answer:

steam distillation

Explanation:

Steam distillation is employed as there is a large difference between boiling points of ortho-and para- nitrophenols. This is due to the presence of intra molecular H- bonding in the case of o- nitrophenol (so high boiling point).
