Chapter 10, Problem 88E

Interpretation Introduction

Interpretation: The positive and negative ends of the given diatomic polar molecule are to be indicated by drawing the molecule.

Concept Introduction: Polar covalent bonds are characterized by having an unequal distribution of electrons of two elements. They also retain a positive and negative pole, which allows them to have certain electronegativity. 

Non-polar covalent bonds are described as having electrons that are similar or nearly equal in terms of number of electrons. This characteristic makes them have none or less electronegativity.

Polar covalent bonds have a charge (from having both positive and negative poles), while non-polar covalent bonds lack the charge.
