Question

(C) The basicity of an ion is determined by the stability of its conjugate acid. Since $H_2S$ is a stronger acid than $H_2O$,the conjugate base $CH_3C

Vedclass · Accepted Answer

$CH_3CH_2S^{-}$ is a weaker base but is more nucleophilic than $CH_3CH_2O^{-}$

Vedclass · Answer

(C) The basicity of an ion is determined by the stability of its conjugate acid. Since $H_2S$ is a stronger acid than $H_2O$,the conjugate base $CH_3CH_2S^{-}$ is a weaker base than $CH_3CH_2O^{-}$.Nucleophilicity is influenced by polarizability and solvation. Sulfur is larger and more polarizable than oxygen,and it is less solvated in protic solvents,making $CH_3CH_2S^{-}$ a stronger nucleophile than $CH_3CH_2O^{-}$.Therefore,$CH_3CH_2S^{-}$ is a weaker base but a more nucleophilic species than $CH_3CH_2O^{-}$.
