Among the following oxoacids, the correct decreasing order of acid strength is:

Options

A. `HOCl gt HClO_(2) gt HClO_(3) gt HClO_(4)`
B. `HClO_(4) gt HOCl gt HClO_(2) gt HClO_(3)`
C. `HClO_(4) gt HClO_(3) gt HClO_(2) gt HOCl`
D. `HClO_(2) gt HClO_(4) gt HClO_(3) gt HOCl`

Answer

C

Explanation

Decreasing order of strength of oxoacids.
`HClO_(4) gt HClO_(3) gt HClO_(2) gt HOCl`
Considered the structure of conjugate bases.

Negative charge is more delocalized on `ClO_(4)^(-)` due to resonance , hence `ClO_(4)^(-)` is more stable (and less basic)
