The strongest conjugate base is

A

`NO_(3)^(-)`

B

`Cl^(-)`

C

`SO_(4)^(2-)`

D

`CH_(3)COO^(-)`

Text Solution

Verified by Experts

The correct Answer is:
D
Weak acid forms strong conjugate base. In `HNO_(3), HCl, H_(2)SO_(4)` and `CH_(3)COOH, CH_(3)COOH` is weakest acid, so its conjugate base is strongest.
`CH_(3)COOH hArr CH_(3)COO^(-)+H^(+)`
