Vedclass · Answer

(A) Nucleophilicity is related to the basicity of the species. Stronger bases are generally better nucleophiles.$1$. $CH_3COO^-$: Acetate ion,resonance stabilized.$2$. $CH_3O^-$: Methoxide ion,strong base.$3$. $CN^-$: Cyanide ion,strong nucleophile.$4$. $CH_3-C_6H_4-SO_3^-$: Tosylate ion,highly resonance stabilized,very weak base.Comparing basicity: $CH_3O^- > CN^- > CH_3COO^- > CH_3-C_6H_4-SO_3^-$.However,in terms of nucleophilicity,$CN^-$ is often a better nucleophile than $CH_3O^-$ in polar aprotic solvents,but generally,the order of nucleophilicity follows the order of basicity for similar species. The correct decreasing order is $3 > 2 > 1 > 4$.

What is the decreasing order of nucleophilicity for the following nucleophiles?
$1. CH_3COO^-$
$2. CH_3O^-$
$3. CN^-$
$4. CH_3-C_6H_4-SO_3^-$ (tosylate ion)
