Question
Chapter 9, Problem 9.7P
Interpretation Introduction
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

The reaction of an aryl amine with nitrite in the presence of perchlorate
produces a diazonium salt. The initial rate of this reaction was measured
using UV spectrometry at 25°C, at fixed initial concentrations of the aryl
amine and perchlorate, but varying the initial concentration of nitrite.
