Conjugate acid of a weak base is always stronger. What will be the decrinsing order of basic strength of the following conjugate bases?
`OH^(-)`,`RO^(-)`,`CH_(3)`,`COO^(-)`,`CI^(-)`

Explanation

The corresponding congugate acids are , `HOH, ROH, CH_(3)COOH,HCI`.
The decrising order of acidic strength , `HCI,CH_(3)COOH,HOH,ROH`
The decrising order of basic strength : `RO^(-),OH^(-),CH_(3)COO^(-),CI^(-)`
Please remember that acidic and basic strengths of the conjugate acids and bases are inversely proportional to each other.
