Hydrogen bonds

Explanation:

Polar molecules are slightly charged (positive or negative). Water is an example of a polar molecule. It has a slightly positive charge toward its hydrogen end, and a slightly negative charge toward its oxygen end. In the water molecule, the hydrogen on one molecule (+) is attracted to the oxygen of a neighboring molecule (-) and thus the two water molecules are kept together. This kind of bond between two molecules is called a hydrogen bond.
