What kind of bond is created by a weak electrical attraction between polar molecules?
This would be called the dipole-dipole interaction.
The predominant intermolecular force between two polar molecules (unless it can undergo the stronger hydrogen bond) is the dipole-dipole interaction.
This type of force occurs between the positive end of one molecule and the negative end of another molecule:
In this image, the slightly positive hydrogen end (slightly positive because it has a lower electronegativity than
If the more electronegative atom (that is bonded to
An example of this hydrogen bonding is seen in plain old water molecules:
