Practice: Determine if the compound of BCl2F is polar or nonpolar.
Polarity of chemical bonds happen in molecules when there is an unequal sharing of electrons.
Concept #1: Molecular Polarity & Perfect Shapes
Both a molecule's shape and bond polarity can affect its overall polarity.
Concept #2: Molecular Polarity
Perfect Shape I: When the central element has no lone pairs and has the same surrounding elements then usually the molecule is nonpolar.
Perfect Shape II: When the central element has same surrounding elements and has a linear or square planar geometry.
Example #1: Determine if carbon tetrachloride, CCl4, is polar or nonpolar.
