WebS N 2 reactions. In primary halogenoalkanes, the carbon that is attached to the halogen is bonded to one alkyl group. These halogenoalkanes undergo nucleophilic substitution by an SN2 mechanism. ‘S’ stands for ‘substitution’. ‘N’ stands for ‘nucleophilic’. ‘2’ means that the rate of the reaction (which is determined by the ... WebA tertiary halogenoalkane ionises to a very small extent of its own accord. Secondary halogenoalkanes do a bit of both of these. Comparing the reaction rates as you change the halogen. You would have to keep the type of halogenoalkane (primary, secondary or tertiary) constant, but vary the halogen.
