How to reference this medium
The strong electronegativity difference between oxygen and hydrogen leads to a shift of electrons in the bonds. There are negative and positive partial charges within the molecule, a so-called dipole structure. This dipole structure within the water molecule is a precondition for the forming of hydrogen bridge bonds.
Information and ideas:
Dipole structure in the water as an example for the electrical dipole moment. In physics, the dipole moment is a measure for spatial charge separation: the higher the charge Q, the higher the dipole moment. The dipole moment is also larger if the charges move further apart (distance from the negative to the positive charge).
