Chapter 9, Problem 20QP

Interpretation Introduction

Interpretation: The polar molecule is to be identified from the given options.

Concept introduction:

The molecular shape of a molecule tells if a molecule is polar or not.

When identical bonds are symmetrically placed around a central atom, the molecule is nonpolar even if the bonds are polar.

Molecules with linear, trigonal, tetrahedral, and octahedral shapes are symmetric. They are nonpolar.

A bond between the atoms of different electronegativity is polar.

A diatomic molecule is polar if the bond is polar.

Bonds in which electron are not shared equally are polar.
