Vedclass · Answer

(C) Nucleophilicity depends on the ability of an atom to donate its lone pair of electrons to an electrophile. In a group,nucleophilicity increases down the group because the larger atom is more polarizable and its electron cloud is less tightly held. Comparing $C_6H_5-O^-$ and $C_6H_5-S^-$,sulfur is larger and more polarizable than oxygen,making $C_6H_5-S^-$ a stronger nucleophile. Comparing $C_6H_5-CH_2^-$ (a carbanion) with the others,the negative charge on carbon is less stable than on oxygen or sulfur due to lower electronegativity,making it highly reactive and a very strong nucleophile. However,in standard comparative contexts for these specific species,$C_6H_5-CH_2^-$ is generally considered the strongest nucleophile among the given options due to the high basicity and reactivity of the carbanion.
