Which of the following correctly describes the relative nucleophilicities of methoxide and tert-butoxide?


A) These alkoxides have essentially the same nucleophilicities since the negative charge in both is localized on an oxygen atom.
B) Methoxide is more nucleophilic because the nucleophilicity of tert-butoxide is diminished by steric effects.
C) tert-Butoxide is more nucleophilic because it contains three methyl groups which increase the charge on its oxygen by donating electron density.
D) tert-Butoxide is more nucleophilic because it is more basic.
E) none of the above
