Polarity of chemical bonds happen in molecules when there is an unequal sharing of electrons.
Molecular Polarity Concept 1
Both a molecule's shape and bond polarity can affect its overall polarity.
Molecular Polarity Concept 2
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.
