`p-`nitrophenol and `o-`nitrophenol are separated by

A

Crystallisation

B

Fractional crystallisation

C

Distillation

D

Steam distillation

Text Solution

Verified by Experts

The correct Answer is:
d
`o-` nitro phenol has intra molecular hydrogen bonding, while `p-`nitrophenol has intermolecular hydrogen bonding `(` comparatively stronger `)` . Due to this reason, the boiling point of `o-`nitrophenol is found quite less than that of `p-`nitrophenol. Hence, `o-`nitrophenol is steam volatile and can be separated from `p-`nitrophenol by steam distillation.
