Solution
The correct option is D The conjugate base of HClO4 is weaker base than H2O The conjugate base of HClO4 has four canonical structures. The negative charge of oxygen is stablized by conjugation.
Cl−O− (Conjugate base of HClO) is not resonance stabilized.
The central atoms Cl in HClO4 and O in HClO respectively are sp3 hybridized.
HClO4 is a stronger acid than H3O+ , so ClO−4 is a weaker base than H2O.
