Which of the Following Correctly Describes the Relative Nucleophilicities of Methoxide

question 49

Multiple Choice

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
