Chapter 9, Problem 9.44P

Interpretation Introduction

Interpretation:

The given bases are to be ranked in the order from slowest $\text{E2}$ reaction rate to the fastest.

Concept introduction:

The rate of $\text{E2}$ reaction generally increases as the strength of the base increases i.e., as $p{K}_a$ of the base’s conjugate acid increases. Strong bases tend to favor $\text{E2}$ reactions.
