Chapter 13, Problem 108E

Interpretation Introduction

Interpretation: The deviation of given molecules from the tetrahedral angle needs to be explained.

  $\begin{array}{l}{\text{CH}}_{\text{4}}\text{(<HCH=109}\text{.5°)}\\ {\text{NH}}_{\text{3}}\text{(<HNH=107}\text{.3°)}\\ {\text{H}}_{\text{2}}\text{O(<HOH=104}\text{.5°)}\end{array}$

Concept Introduction:

Lewis dot structure is the representation which shows the bonding between atoms present in a molecule. It shows lone pairs and bond pairs that existing on each bonded atom. Lewis dot structure is also known as Lewis dot formula or electron dot structure.

The hybridization and molecular structure of molecule determine the molecular structure of molecule.

VSEPR theory states that if there is certain number of lone pair on the central atom, it shows deviation from the standard shape to reduce the repulsion between lone pair and bond pair of the central atom.
