transition state. The main factors that affect heterolysis rates are mainly the solvent's polarity and electrophilic as well as its ionizing power. The polarizability, nucleophilicity and cohesion of the solvent had a much weaker effect on heterolysis. However, there is some debate on effects of the nucleophilicity of the solvent, some papers claim it has no effect, while some papers claim that more nucleophilic solvents decrease the reaction rate.
