Chapter 7.5, Problem 6PPB

Interpretation Introduction

Interpretation:

The bonding and the bond angle of ${\text{BeF}}_2$ molecule should be explained on the basis of hybrid orbital theory.

Concept introduction:

• Hybridization is the mixing of valence atomic orbitals to get equivalent hybridized orbitals that having similar characteristics and energy.
• The bonds between atoms are formed by sharing their electrons through the overlap of atomic orbitals between other atoms.
• The each overlapping atomic orbital must be contained with a single unpaired.
• The electron carried by each overlapping atomic of must have opposite spins.
• Formation of a bond between atoms should have lower potential energy as compared to the sum of potential energies of individual atoms.
• The bond angle of bonds is depends upon the angle between overlapping orbitals and lone pairs of central atom.

To explain: The bonding of ${\text{BeF}}_2$ molecule and the bond angle for the given molecule using the concept of hybrid orbital theory.
