The ${\mathrm{S}}_{\mathrm{N}}1$ reactions takes place via formation of carbocation. The speed of the reaction depends on the stability of carbocation. Electron releasing groups supports the ${\mathrm{S}}_{\mathrm{N}}1$ reactions. The ${\mathrm{S}}_{\mathrm{N}}2$ reactions are takes place through the formation of transition state. The transition can be stabilised by electron withdrawing groups.
