WebJan 23, 2024 · A greater number of double bonds, or degree of unsaturation, in the molecules results in a lower melting point, because the van der Waals forces are less effective. The efficacy of van derWaals forces depends on the ability of molecules to pack closely together. Following are the characteristics of Van Der Waal forces. 1. These forces are additive. 2. They are weaker than ionic, covalent bonds. 3. Van Der Waals forces are not directional. 4. They work in a short range. The interaction increases when molecules are closer. 5. These forces are independent of temperature. The … See more Electrons are distributed throughout an atomor molecule. Moreover, electrons are always moving. At any moment there can be uneven … See more Primarily there are three types of Van Der Waal forces. Following are the list of those. 1. Dipole-dipole Forces Dipole is a polar molecule in … See more The strength of these forces usually ranges between 0.4 kJ/mole and 4 KJ/mole. Moreover, they act over a distance of less than O.4 nm. However, the net effect of these forces is repulsive because electron … See more The strength of these forces mainly depends on the following factors. 1. Size of the Molecule-If you look at the periodic table, you will see that the boiling point of noble gases increases, as you go down. It happens because … See more
