Polar and Non-Polar Bonds.

polar bond

the electrons forming the bond are unequally distributed.

non-polar bond

the electrons forming the bond are equally distributed.

water is a...

polar bond

carbon dioxide is a..

non-polar bond

polarity

separation of regions in a molecule

bond dipole

difference in electronegativities between 2 atoms within a molecule

molecule dipole

overall separation of (+) and (-) regions on a molecule

dipole

HF

H and F atoms are connected by a very polar covalent bond; F "hogs" the electrons
