Van der Waals forces refer to the sum of the intermolecular forces acting between molecules of covalently bonded compounds. In some cases, there are more than one force, as in polar compounds; in non-polar compounds there is only one type of force present. The van der Waals forces include hydrogen bonding, dipole-dipole interaction, and London dispersion forces.
Dipole-dipole attraction and van der Waals forces.
Yes, van der Waals forces are generally weaker than chemical bonds. Van der Waals forces are intermolecular forces that result from temporary fluctuations in electron distribution, while chemical bonds involve the sharing or transfer of electrons between atoms to form more stable structures.
London dispersion forces.

Van der Waals forces are usually considered to includedipole - dipole interactionsdipole- induced dipole interactionsinstantaneous dipole - induced dipole interactions (London dispersion forces)These are electrostatic in nature, and cause an attraction between molecules
They are named after Johannes Diderik van der Waals who was the first to postulate about inter molecular forces
London dispersion forces and van der Waals forces are related but not exactly the same. London dispersion forces are a type of van der Waals force that occurs between all molecules, while van der Waals forces encompass a broader category of intermolecular forces that also include dipole-dipole interactions and hydrogen bonding.
Van der Waals forces are a broader term that includes London dispersion forces as a subset. London dispersion forces are the weakest type of van der Waals forces and are caused by temporary fluctuations in electron distribution. Van der Waals forces also include dipole-dipole interactions and hydrogen bonding, which are stronger than London dispersion forces.

van der Waals forces of attraction
Van der Waals forces are weaker than chemical bonds. Van der Waals forces are caused by temporary fluctuations in electron distribution and are present in all molecules, while chemical bonds involve sharing or transferring electrons to form stable connections between atoms. Chemical bonds are generally stronger than van der Waals forces.

Dipole-dipole attraction and van der Waals forces.
London dispersion forces would affect the melting point the least as they are generally weaker than dipole-dipole and hydrogen bonding forces.
London dispersion forces or van der Waals forces predominate in octane. These forces result from temporary shifts in electron density, causing temporary dipoles which attract other molecules.
