The formula for alcohol (ethanol) is CH3CH2OH. The OH group has a polar bond, as in water, because the oxygen atom is more electronegative than the hydrogen atom. This means the oxygen has a greater attraction for the shared electrons in the bond than the hydrogen does. The oxygen therefore carries a slight negative charge, leaving the hydrogen with a slight positive charge ie the bond is polar.
The polar OH group can then form hydrogen bonds with water, allowing the two substances to mix with each other.
