Chapter 14, Problem 79AE

Interpretation Introduction

Interpretation: The Lewis structure of given molecules needs to be determined and the molecules with following properties needs to be determined.

• At least one bond angle approximately 120°
• Compound that exhibit sp³ hybridization by central atom
• Compound with linear molecular structure.

  ${\text{SeO}}_{\text{2}}{\text{, PCl}}_{\text{3}}{\text{, NNO, COS, PF}}_3$

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 sum of valence electrons must be arranged in such a way that all atoms must get octet configuration (8 electrons).

  $\text{Hybridization = Number of sigma bonds + Number of lone pairs on bonded atoms}\text{.}$

The polarity of molecule is determined with the help of presence of polar bond and symmetrical geometry.
