The decreasing order of `pK_(a)` value of the folliwng is:

A

`(III) gt (I) gt (II)`

B

`(II) gt (I) gt (III)`

C

`(I) gt (III) gt (II)`

D

`(I) gt (II) = (III)`

Text Solution

Verified by Experts

The correct Answer is:
`b`

Stable the `C_(B)` stronger is the acidic sterngth (lower `pK_(a)`)
Therefore, the decreasing `pK_(a)` value: `(II) gt (I) gt (III)`
