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

Conjugate base of a weak acid is a strong base and conjugate base of a strong acid is a weak base.
`RO^(-) > OH^(-) > CH_3COO^(-) > Cl^(-)`
