The main reason acting here is Dipole Moment. The higher the dipole moment of a molecule, the greater will be the intermolecular attractive forces and the higher will its boiling point be. Dipole moment is the displacement of electron density in a molecule and it is a vector quantity. The net dipole moment of a molecule is the vector summation of all the ...

In non-polar liquids, the intermolecular forces are known as London dispersion forces (or dipole induced dipole interaction). This is the weakest interaction that exists between molecules. The strength of this interaction depends on polarisability of non-polar molecule. As an example, let's take the following examples: $$ \begin{array}{lr|lr|lr|lr} \hline \...

The polarity of the compound is a measure of the difference in dipole moment across the molecule. Think of it as a see-saw with a non polar compound being balanced and a polar compound having one end heavier than the other. As the polarity increases, the relative attraction of the partial negative side of the molecule to the partial positive side of the same ...
