Solution
Both assertion and reason are correct statements but reason is not correct explanation of assertion.
Explanation:
In o-nitrophenol there is intramolecular H-bonding.
Thus, o-nitrophenol does not form H-bond with \[\ce{H2O}\] but m-nitrophenol and p-nitrophenol form H-bonds with \[\ce{H2O}\]. Also, due to intermolecular H-bonding m-nitrophenol and p-nitrophenol exist as associated molecules.
