In aprotic dipolar solvents the carboxylate anion exists as desolvated one whereas in protic solvents the nucleophile is solvated by hydrogen-bonding thereby decreasing the nucleophilicity of the active species. The correlation of the rate constants with various solvent parameters has been checked.
