Chapter 7.4, Problem 7.4CE

Interpretation Introduction

Interpretation:

The reason for not having a pi bonding for an ${\text{sp}}^{\text{3}}$ hybridization has to be given.

Concept introduction:

Sigma (σ) bonds are the bonds in which shared hybrid orbital’s electron density are concentrated along the internuclear axis.

Pi (π) bonds are the bonds in which shared unhybridized orbital’s (p, d, etc) electron density are concentrated in above and below of the plane of the molecule.

${\text{sp}}^{\text{3}}$ hybrid orbitals is produced by hybridization of single s-orbital and three p-orbital.
