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 … 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.

WebThe conjugate base to water is the hydroxide anion, OH-, and this is a bad leaving group. So hydroxide ion is a bad leaving group and that's because water is not a strong acid. Look at this value for the pKa, positive 15.7. So if we look at ethanol, similar story here. So ethanol has a pKa value of positive 16.
