Which of the following is more nucleophilic and why? CH30 (CH3)3CO 1 2 Compound 2, because its nucleophilicity is increased by the adjacent CH3 groups. Compound 2 because it is a stronger base. Compound 1, because the nucleophilicity of compound 2 is decreased by steric effects. Compound 1, because it has a weaker conjugate acid. O They actually have about the same nucleophilicity since in both, the negative charge is localized on an oxygen atom.
