Chapter 11.2, Problem 5P

Interpretation Introduction

Interpretation:

The two compoundsout of five given compounds that yield the same carbocation on ionization are to be chosen.

Concept Introduction:

>

For a ${\text{S}}_{\text{N}}\text{1}$ reaction, the reaction follows the first order rate law. In the first step, the stable carbocation is formed.

>

Allylic carbocations can be stabilized by electron delocalization.

>

In all resonance contributing structures, the connectivity of atoms must be the same.The contributing structures must have the same number of electrons and the same net charge and unpaired electrons.
