Covalent/Molecular Compounds

All molecular compounds are either polar or nonpolar

Page 3: Polar vs. Non Polar Molecules. Covalent/Molecular Compounds All molecular compounds are either polar or nonpolar.

Polar Molecules

In polar molecules, electrons are not shared equally.

Page 5: Polar vs. Non Polar Molecules. Covalent/Molecular Compounds All molecular compounds are either polar or nonpolar.

Bond PolarityA bond is polar if it has a dipole moment.

Bond Dipole Moment: The electrons in a covalent bond connecting two different atoms are not equally shared by the atoms due to the electronegativity difference between the two elements.

If F, O, N, or Cl is bonded to a nonmetal other than itself, then the bond has a dipole

*** N Cl = no dipole

Nonpolar MoleculesMolecules without positive and negative

sides (dipole)

Symmetrical or the same on their exterior

Causes of Polarity

1. Asymmetrical shapeTrigonal pyramidalBent

2. Unshared e- on the central atom

3. Polar bonds (see slide 5)
