Chapter 9, Problem 82AP

Interpretation Introduction

Interpretation:

The Lewis structure of ${\text{BeCl}}_{\text{4}}{}^{2-}$, its geometry, and the hybridization of the $\text{Be}$ atom are to be explained.

Concept introduction:

Hybridization is the combination of atomic orbitals to form hybrid orbitals.

To determine the hybridisation of an atom, draw the Lewis structure of the molecule.

Find the number of electron domains around an atom so as to get the number of hybrid orbitals that are used by the atom for bonding.

When atomic orbitals combine, they form an equal number of hybrid orbitals.

The s orbital combines with one, two, or three p orbitals to form $\text{sp,}{\text{sp}}^{\text{2}},{\text{or sp}}^{\text{3}}$

hybrid orbitals, respectively.
