Witryna11 maj 2024 · 1 Answer. From what I learned in organic I, their nucleophilicity does not change with the solvent because if the solvent is polar Protic, each nucleophile will be hindered in a similar manner (due to the solvent cage). If the solvent is polar aprotic, this hindrance does not matter. In both cases, nucleophilicity matches base strength.

WitrynaThe polar protic character of MeOH weakens the H-bonding interactions, while MeCN as an aprotic solvent weakens the aromatic π-π interactions and strengthens the ionic interactions.
