WebSn1 reactions depend on the stability of the cation formed when the Leaving group had left. So, since tertiary carbocations are most stable of the three will undergo Sn1 reaction easily. Order: Tertiary > Secondary > Primary Sn2 reactions depend on the fastness of the leaving group. The fastness depends on the Leaving group. WebBimolecular elimination reaction (E2) follows second-order kinetics. Bimolecular elimination reaction (E2) occurs in a single step. The reaction rate depends on the concentration of substrate, i.e. alkyl halide and a base. Rate of Reaction = k [Substrate] [Base]. It is dependent on the strength of the base.
