How do scientists predict the polarity of molecules, the distribution of non-polar and polar molecules?

The scientists predict the polarity of molecules and the distribution of non polar and polar molecules by finding out the net dipole moment of the molecular structure.

Explanation:

The net value of dipole moment is found out with the help of finding the bond angle between the atoms of the given molecule along with the distance between the atoms and the charge on the atoms of the molecule.

This will be applied in the appropriate formula which tells whether the molecule is polar or non polar.
