Chapter 9, Problem 19QP

Interpretation Introduction

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

Concept introduction:

With the help of the shape of a molecule, its polarity can be determined.

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

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

When an electronegativity difference is present, the molecule is polar.

A diatomic molecule is polar if the bond is polar.
