How can be mixture of o-nitrophenol and p-nitrophenol separated ?

1.	How can be mixture of o-nitrophenol and p-nitrophenol separated ?
Answer» While separating a mixture of ortho and para nitrophenols by steam distillation, o-nitrophenol will be steam volatile due to presence of intramolecular hydrogen bonds. In case of p-nitrophenol, intermolecular hydrogen bonding is present which results in strong association of molecules. Hence, p-nitrophenol is not steam volatile.
