Molecular Polarity For larger molecules, electronegativity and the molecular shape is considered for determining the polarity of a molecule.

Molecular Polarity Rules of thumb for determining molecular polarity: If the central atom has nonbonding pairs of electrons, the molecule is polar . If the central atom has no nonbonding pairs of electrons and: all other atoms connected to the central atom are identical, the molecule is nonpolar . at least one of the atoms connected to the central atom is different from the others, the molecule is polar .
