Chapter 12, Problem 66DSP

Interpretation Introduction

Interpretation:

Based on the given $\text{ρ}$ values, the series of reactants in which there is a greater degree of $\text{C-H}$ bond breaking at the transition state is to be determined.

Concept introduction:

A positive value of reaction constant indicates that the transition state has more negative charge than the reactant.

A negative value of reaction constant indicates that the transition state has more positive charge than the reactant.

$\text{E2}$ elimination reaction is a one-step reaction.

The breaking of $\text{C-H}$ bond, formation of a new pi bond, and the departure of the leaving group occur in the single step.
