Question

Name the method used to separate ortho nitrophenol

Answer 1

Answer:

In o-nitrophenol, intra-molecular hydrogen bonding is present.

It is because of the polar nature of the O-H bonds which result in the formation of hydrogen bonds within the same molecule.

This intramolecular H bonding decreases water solubility and increases volatility.

In p-nitrophenol, inter molecular hydrogen bonding is possible.

Due to inter molecular hydrogen bonding, p-nitrophenol undergoes association which result in an increase in the molecular weight and decreasing volatility.

Thus o-nitrophenol is obtained by steam distillation while p-nitrophenol is not.
