The strongest Van Der Waals forces is the hydrogen bond. These forms a permanent dipole-dipole attraction, and there bond occur between the hydrogen and end of one molecule of fluorine, oxygen, or nitrogen.
Helium has the weakest Van der Waals forces among these noble gases. This is because helium is a monatomic gas, meaning it has only one atom per molecule, resulting in weaker Van der Waals interactions compared to larger noble gases like argon, krypton, and neon.
Noble gases are mono atomic and are non polar. They are hence held together by van der Waals forces of attraction which is a weak force of attraction.
The melting and boiling points increase down the group because of thevan der Waals forces. The size of the molecules increases down the group. This increase in size means an increase in the strength of the van der Waals 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.

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.
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.
