Q. p-nitrophenol and o-nitrophenol are separated by:
BVP MedicalBVP Medical 2004
Solution:
o-nitrophenol has intra molecular hydrogen bonding, while p-nitrophenol has intermolecular hydrogen bonding (comparitively 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.
