AIIMS 2008 Chemistry Acidity Assertion Reason Question
Assertion: Anilinium chloride is more acidic than ammonium chloride. Reason: Anilinium chloride is resonance stabilised.
Both Assertion and Reason are true and Reason is the correct explanation of Assertion.
Both Assertion and Reason are true but Reason is not the correct explanation of Assertion.
Assertion is true but Reason is false.
Both Assertion and Reason are false.
Correct Answer
Detailed Explanation
Aniline is weaker base than ammonium chloride. In NH4Cl or aliphatic amines, then non-bonding electron pair of N is localised and is fully available for coordination with a proton. On the other hand, in aniline and other aromatic amines, the non-bonding electron pair is delocalised into benzene ring by resonance. But anilinium ion is less resonance stabilised than aniline.
