A

`H_(2)SO_(3)`

B

`H_(2)SO_(4)`

C

`HCIO_(3)`

D

`HCIO_(4)`

Text Solution

Verified by Experts

The correct Answer is:
D
Electronegativity of Cl is hihger than that of S. Further the conjugate base of `HClO_(4)` is more stable than `H_(2)SO_(4)`. Thus `HClO_(4)` is more acidic than `H_(2)SO_(4)`.
