In the following question, a statement of Assertion (A) followed by a statement of Reason (R) is given. Choose the correct answer out of the following choices:
Assertion (A): o-Nitrophenol is less soluble in water than the m- and p-isomers.
Reason (R): m-Nitrophenol and p-Nitrophenol exist as associated molecules.
(i) Assertion and reason both are correct and reason is the correct explanation of assertion.
(ii) Assertion and reason both are wrong statements.
(iii) Assertion is a correct statement but reason is a wrong statement.
(iv) Assertion is a wrong statement but reason is a correct statement.
(v) Both assertion and reason are correct statements but reason is not the correct explanation of assertion.
(v)Both assertion and reason are correct statements but reason is not the correct explanation of assertion.
Intramolecular H-bonding is present in o-nitrophenol.
Thus, m-nitrophenol and p-nitrophenol form H-bonds with H2O but o-nitrophenol does not. Also, m-nitrophenol and p-nitrophenol exist as associated molecules because of the presence of intermolecular H-bonding.
