NEET2006ChemistryGeneral Organic ChemistryActual
Assertion : Anilinium chloride is more acidic than ammonium chloride. Reason : Anilinium ion is resonance-stabilised.
Options
- AIf both assertion and reason are true and reason is the correct explanation of the assertion
- BIf both assertion and reason are true but reason is not the correct explanation of the assertion
- CIf assertion is true, but reason is false
- DBoth assertion and reason are false statements.
Correct answer
C. If assertion is true, but reason is false
Step-by-step solution
Aniline is weaker base than ammonium chloride. In NH ₄ Cl or aliphatic amines, the non-bonding electron pair of N is localized and is fully available for coordination with a proton. On the other hand, in aniline or other aromatic amines, the non-bonding electron pair is delocalised into benzene ring by resonance.
