Kc1 chemistry.

Polar molecules will be attracted to each other by either hydrogen bonding or dipole-dipole interactions. These intermolecular forces are made possible by a large difference in electronegativity values for two atoms bonded to each other. In water, the electronegativity difference between oxygen (3.5) and hydrogen (2.1) is 1.4 (3.5-2.1=1.4).
