Chapter 8, Problem 8.102CP

Interpretation Introduction

Interpretation:

Overall shape of the borazine molecule needed to be determined

Concept introduction:
Count the number of sigma bond and lone pair present on atom.
Number of $\sigma \text{ bond}$ and lone pair $=2$ , then hybridization $=\text{ sp}$

Number of $\sigma \text{ bond}$ and lone pair $=3$ , then hybridization $={\text{ sp}}^2$

Number of $\sigma \text{ bond}$ and lone pair $=4$ , then hybridization $={\text{ sp}}^3$

Hybridization and Geometries according to VSEPR theory

  $\begin{array}{l}\text{Hybridization Geometry Bond angle}\\ {\text{ sp linear 180}}^{°}\\ {\text{ sp}}^2{\text{ trigonal planar 120}}^{°}\\ {\text{ sp}}^3\text{ tetrahedral 109}{\text{.5}}^{°}\end{array}$
