STANDARD Chemistry Acidity of Phenols Assertion Reason Question
Given below are two statements: Statement-I: The acidic strength of monosubstituted nitrophenol is higher than phenol because of electron withdrawing nitro group. Statement-II: o-Nitrophenol, m-nitrophenol and p-nitrophenol will have same acidic strength as they have one nitro group attached to the phenolic ring. In the light of the above statements, choose the most appropriate answer from the options given below:
Both Statement-I and Statement-II are correct
Both Statement-I and Statement-II are incorrect
Statement-I is correct but Statement-II is incorrect
Statement-I is incorrect but Statement-II is correct
Correct Answer
Detailed Explanation
Statement-I is correct as the nitro group increases acidity by stabilizing the phenoxide ion. Statement-II is incorrect because the position of the nitro group affects acidity; ortho-nitrophenol is more acidic due to intramolecular hydrogen bonding.
