Chapter 5.9, Problem 14P

Interpretation Introduction

Interpretation:

The number of bonded pairs of electrons involved in stabilization of ${\text{R}}_{\text{3}}{\text{C}}^{\text{+}}$, ${\text{R}}_{\text{2}}{\text{CH}}^{\text{+}}$, and ${\text{RCH}}_{\text{2}}$ by hyperconjugation is to be determined.

Concept introduction:

The positive charge of a carbocation can be stabilized by delocalization through hyperconjugation.

Hyperconjugation involves electron pairs of bonds that are $\text{β}$ to the positively charged carbon atom.
