F332 - Module 1 (ES) Elements from the Sea

Reaction mechanisms

Explain and use the terms: hydrolysis, substitution, nucleophile;

Use the SN2 mechanism as a model to explain nucleophilic substitution in halogenoalkanes using ‘curly arrows’ (knowledge of the SN1 mechanism or of the SN1 or SN2 nomenclature is not required);

Explain how either bond enthalpy or bond polarity might affect the relative reactivities of the halogenoalkanes and explain how experimental evidence determines that the bond enthalpy is more important;
