Vedclass · Answer

(C) Nucleophilicity depends on the availability of the lone pair and the stability of the negative charge.$1$. $CH_3O^-$ is a strong nucleophile because the negative charge is localized on the oxygen atom.$2$. $CN^-$ is a strong nucleophile due to the high polarizability of the carbon atom.$3$. $CH_3COO^-$ has the negative charge delocalized over two oxygen atoms via resonance,making it less nucleophilic than $CH_3O^-$.$4$. $CH_3C_6H_4SO_3^-$ (tosylate ion) has the negative charge highly delocalized over three oxygen atoms,making it a very weak nucleophile.Comparing these,the order is: $CH_3O^- > CN^- > CH_3COO^- > CH_3C_6H_4SO_3^-$.Thus,the correct order is $(ii) > (iii) > (i) > (iv)$.

The decreasing order of nucleophilicity among the following nucleophiles is:
$(i) CH_3COO^-$
$(ii) CH_3O^-$
$(iii) CN^-$
$(iv) CH_3C_6H_4SO_3^-$
