Problem

 Which of the following molecules or ions contain polar bonds?

(a) O3           (b) S 8           (c) O  22−           (d) NO 3           (e) CO 2           (f) H 2S           (g) BH 4

Solution

First, look at the atoms in each compound then compare their electronegativity differences.

Calculate their electronegativity difference (you can find their electronegativity values in your books or on the internet:

0.1 – 0.4  nonpolar covalent
