Vedclass · Answer

(B) The strength of a conjugate base is inversely proportional to the strength of its corresponding acid.$1$. $Cl^{-}$ is the conjugate base of $HCl$ (a strong acid).$2$. $CH_3COO^{-}$ is the conjugate base of $CH_3COOH$ (a weak acid).$3$. $SO_4^{2-}$ is the conjugate base of $HSO_4^{-}$ (a moderately strong acid).$4$. $NO_2^{-}$ is the conjugate base of $HNO_2$ (a weak acid).Comparing the acid strengths: $HCl > HSO_4^{-} > HNO_2 > CH_3COOH$.Therefore,the order of basicity of their conjugate bases is: $CH_3COO^{-} > NO_2^{-} > SO_4^{2-} > Cl^{-}$.$CH_3COO^{-}$ is the strongest conjugate base among the given options.
