Interpretation:
For the given E2 elimination reaction, two bases shown, A and B, are to be matched with their respective rate constants according to their pKa values.
Concept introduction:
Higher the pKa value, the weaker the acid and stronger its conjugate base.
As the strength of base increases, it will abstract an acidic proton more rapidly.
An E2 reaction is a single step, bimolecular reaction involving both the substrate and the base. Since the deprotonation and the departure of the leaving group occur simultaneously, the
