प्रश्न
Account for the following :
HClO4 is a stronger acid than HClO.
उत्तर
HClO4 is a stronger acid than HClO. This is because ClO−4ClO4- is a weaker conjugate base than ClO−. In ClO−4ClO4-, the negative charge is spread over four oxygen atoms owing to resonance. Hence, it is more stable than ClO−.
