Web1. For two nucleophiles with the same nucleophilic atom, the stronger base is the stronger nucleophile 2. A negatively charged nucleophile is always stronger than its conjugate acid 3. Right-to-left across a row of the periodic table, nucleophilicity increases as basicity increases Steric hindrance is... WebHard nucleophiles are small, have high charge densities, and are weakly polarizable. Examples are ROH, RO⁻, RNH₂, NH₂⁻, and F⁻ Their orbitals do not necessarily overlap very well with the electrophile's accepting orbital, but the electrostatic attraction directs them and aids the reaction.
