Polarity
Polarity is the measure of an atoms pull on shared electrons. The more protons in an atoms nucleus increases the electronegativity thus increasing the pull on the atoms which indicates unequal sharing of the electrons.
The bonds between C - H, C-C are nonpolar, but the O - C and the single O - H bond is polar.
