Question
Which of the following correctly describes the relative nucleophilicities of methoxide
and tert-butoxide?
tert-Butoxide is more nucleophilic because it is more basic.
Methoxide is more nucleophilic because the nucleophilicity of tert-butoxide is
diminished by steric effects.
These alkoxides have essentially the same nucleophilicities since the negative
charge in both is localized on an oxygen atom.
tert-Butoxide is more nucleophilic because tert-butanol has a larger acid
dissociation value than methanol.
tert-Butoxide is more nucleophilic because it contains three methyl groups
which increase the charge on its oxygen by donating electron density.
