Chapter 9, Problem 122RQ

Interpretation Introduction

Interpretation:

The group of an element, based on its molecular shape is to be identified.

Concept Introduction:

VSEPR theory is helpful in predicting the shapes of molecules from their Lewis structures. The geometry of a molecule can be determined on the basis of the number of electron groups, lone pairs, and bonding pairs in that molecule.

An electron domain can be defined as the region or a space near the nucleus of an atom where electrons can be found. The electron domain describes the non-bonding domain as a lone pair, or a free radical.

As per the electron domain, the space covered by a bonding domain will be in the increasing order for the molecules having a single bond, a double bond, and a triple bond.
