In biology, depolarization or hypopolarization [1] [2] is a change within a cell, during which the cell undergoes a shift in electric charge distribution, resulting in less negative charge inside the cell compared to the outside.
This occurs if there is symmetry within the molecule that causes the dipoles to cancel each other out. This occurs in molecules such as tetrachloromethane and carbon dioxide. The dipole–dipole interaction between two individual atoms is usually zero, since atoms rarely carry a permanent dipole. The Keesom interaction is a van der Waals force.
The bent molecule H 2 O has a net dipole. The two bond dipoles do not cancel. The overall dipole moment of a molecule may be approximated as a vector sum of bond dipole moments. As a vector sum it depends on the relative orientation of the bonds, so that from the dipole moment information can be deduced about the molecular geometry.

The dipoles do not cancel out, resulting in a net dipole. The dipole moment of water depends on its state. In the gas phase the dipole moment is ≈ 1.86 debye (D), [11] whereas liquid water (≈ 2.95 D) [12] and ice (≈ 3.09 D) [13] are higher due to differing hydrogen-bonded environments.
