Vedclass · Answer

(C) Nucleophilicity is related to the basicity of the species. Stronger bases are generally better nucleophiles.$1$. $CH_3O^-$ is a strong base (conjugate base of a weak acid $CH_3OH$).$2$. $CN^-$ is a strong nucleophile due to the high electron density on carbon.$3$. $CH_3COO^-$ is a weaker base than $CH_3O^-$ due to resonance stabilization.$4$. $CH_3-C_6H_4-SO_3^-$ (tosylate ion) is a very weak base because its negative charge is highly delocalized over three oxygen atoms.Comparing the basicity: $CH_3O^- > CN^- > CH_3COO^- > CH_3-C_6H_4-SO_3^-$.However,in terms of nucleophilicity in polar protic solvents,$CN^-$ is often considered very effective. Based on standard trends of nucleophilicity (where $CH_3O^-$ is a stronger nucleophile than $CN^-$ in many contexts,but $CN^-$ is highly reactive),the order is $B > C > A > D$.

What is the decreasing order of nucleophilicity for the following nucleophiles?
$A = CH_3COO^-$
$B = CH_3O^-$
$C = CN^-$
$D = CH_3-C_6H_4-SO_3^-$
