2. If the molecule has only one bond, determine polarity of the bond. Nonpolar bond, will
give nonpolar molecule and polar bond will give polar molecule.
Examples:
а. Н2
b. HCI
1
3. Molecules with more than one bond
A. The molecule is symmetrical: If there are no lone pairs on the central atom, and if all the
bonds to the central atom are the same, the molecule is nonpolar.
Examples:
1. СО2
2. BF3
3. CCI4
