Question

Arjun nitrophenol and para nitrophenol which is more volatile explain

Answer 1

o-Nitrophenol forms intramolecular H bond whereas molecules of p-Nitrophenol get associated through intermolecular H bond. During boiling, the strong intermolecular H bonding increases the boiling point but intramolecular H bonding cannot do so.

Therefore, o-Nitrophenol is more steam volatile than p-Nitrophenol.
