In SN2 reactions, nucleophile approach to the carbon bearing the leaving group, the presence of bulky substituents inhibits the incoming nucleophile which decrease the rate of reaction, therefore, alkyl halides having bulkier substituents or higher degree alkyl halides preferably react through SN1 path. The order of reactivity for SN1 path is 1°>2°>3
