WebWhat is surprising is the magnitude of the secondary KIE at 180 °C (1.72)! To our knowledge, this is among the largest secondary KIE measured. The fact that this substantial secondary KIE occurs ... WebSince the change in bond order is greater between initial state and S N 1 transition state than between ground state and S N 2 transition state, S N 1 will have a greater kinetic isotope effect. Measuring the KIE of an unknown reaction and comparing it to the KIEs of reactions with known mechanisms will therefore distinguish between S N 1 and S ...
