Hydrogen bonding results in two processes which we see as and

Disassociation, polarization and attraction

Explanation:

In an hydrogen bond, the hydrogen act as partially positive atom while the other element to which it is bonded act as partially negative atom. This second element other than the hydrogen can be oxygen, fluorine, chlorine etc.

First the hydrogen bonds disassociates and polarizes thereby forming two poles one positive and the other one negative.

The positive poles now try to attract the negative pole of other molecule of the same substance or any other substance. The same happens with the negative pole also.
