Chapter 3, Problem 83E

Interpretation Introduction

Interpretation: The Lewis structure is to be drawn for the given molecules.

Concept introduction: The Lewis structure is also known as dot structure. This structure depicts the bonding between atoms and the lone pairs of electrons if exists.

The octet rule states that atoms or molecules gain or lose electrons to get the electronic configuration of nearest noble gas.

To determine: The Lewis structure of the molecule ${\text{BeH}}_2$ and ${\text{BH}}_3$
