Chapter 3, Problem 10CTQ

Interpretation Introduction

Interpretation: Total valence electrons found in cation ${\text{H}}_{\text{3}}{\text{C}}^{\oplus }$ should be determined.

Concept introduction: A carbocation is a planar system and therefore $s{p}^2$ hybridized with vacant unhybridized p -orbital. There are three $s{p}^2$ and $1s$ overlaps; each shows that $s{p}^2$ hybrid orbital with one electron overlaps with $1s$ orbital of hydrogen that has electron in antiparallel spin so that a stable sigma bond formation may occur as illustrated below:
