Question

Assertion : Boiling point of $p$-nitrophenol is greater than that of $o$-nitrophenol.\ Reason : There is intramolecular hydrogen bonding in p-nitrophenol and intermolecular hydrogen bonding in $o$-nitrophenol.

Professor PC Thomas Classes · Answer

(c) : There is intermolecular hydrogen bonding in $p$-nitrophenol and intramolecular hydrogen bonding in $o$-nitrophenol. As intramolecular hydrogen bonding in $o$-nitrophenol prevents further association, it has lower boiling point than $p$-nitrophenol.
