Chapter 13, Problem 114AE

Interpretation Introduction

Interpretation: The complete Lewis structure of ${\text{TeF}}_{{}_5}^{-}$ needs to be determined and the distortion from the ideal square pyramidal structure needs to be explained.

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.

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

For a molecule to be polar, it should have polar bond with no symmetry in the molecule.
