If such a charge separation exists, the molecule is said to be a polar molecule (or dipole); otherwise the molecule is said to be nonpolar. The bond moments will be maximized when the electronegativity difference is greatest. Step 1: Determine the valence electrons for each participating atom: It is four for carbon and six for both oxygen as well as sulfur.
