This is possible because electrical charges (positive or negative) are non-uniform distributed in the molecule.
A molecule can have a very strong molecular dipole if it has highly polarized bonds, such as between atoms with large differences in electronegativity. Additionally, having a symmetrical geometry that enhances the overall dipole moment can also contribute to a strong molecular dipole.
This is possible because electrical charges (positive or negative) are non-uniform distributed in the molecule.
A molecule with a polar covalent bond, such as hydrogen fluoride (HF) or hydrogen chloride (HCl), will have a very strong dipole-dipole force due to the difference in electronegativity between the bonded atoms. This creates a significant imbalance in charge distribution within the molecule, resulting in a strong attraction between the positive and negative ends of neighboring molecules.

Toluene has a dipole moment because it is a polar molecule. This is due to the difference in electronegativity between the carbon and hydrogen atoms. The net dipole moment in toluene is not very strong because the polarity of the C-H bonds cancel each other out to some extent.

Yes, nitrogen gas (N2) does not have a dipole moment because it is a linear molecule with equal and opposite nitrogen atoms, resulting in a symmetrical distribution of charge. This symmetry cancels out any potential dipole moment in the molecule.
When the range of electronegativity between the atoms are really high. For example, hydrogen has 2.20 elctronegativity and fluorine has 3.98 and the range between them is 1.78. Compared to like nitrogen (3.04) and oxygen (3.44), whose range is 0.4, the hydrogen and fluorine will have a strong dipole-dipole force.
The strongest intermolecular force is Hydrogen Bonding! Hydrogen atoms have a very strong attraction to Fluorine, Oxygen, and Nitrogen atoms, a molecule with Hydrogen and a molecule with F, O, or N will form strong hydrogen bonds. Just remember FON or NOF. (It's important to note that hydrogen bonding does NOT occur with hydrogen atoms that are bonded to carbon atoms.) The second strongest is dipole-dipole attraction. Some molecules are polar, meaning they have a positive and negative pole, kind of like magnets. And just like magnets, two polar molecules attract because one's negative pole is attracted to the other's positive pole. The weakest of them all is London Dispersion force. This force exists between all molecules, no matter what atoms are in them. Basically, as electrons fly around the nuclei of atoms, they'll often create a very weak dipole that exists only for a tiny fraction of a second. Basically these LD forces are just like D-D forces except weaker.
