Polar Bonds and Molecules

Polar Bonds and Molecules. Chapter 8 Section 4. Bond Polarity. Covalent bonds involve electron sharing between atoms. However, covalent bonds differ in terms of how the bonded atoms share the electrons. There is a constant tug of war on the electrons in a covalent bond. Bond Polarity.

Predicting Molecular Polarity

Predicting Molecular Polarity. When there are no polar bonds in a molecule, there is no permanent charge difference between one part of the molecule and another, and the molecule is nonpolar.
