Phenol hydrogen bonding

Webo-nitrophenol is more volatile due to intramolecular hydrogen bonding. p-nitrophenol is less volatile and has a high boiling point due to intermolecular hydrogen bonding. When phenol is treated with concentrated nitric acid, the nitration results in the formation of 2, 4, 6-trinitrophenol (commonly called picric acid). 2.
