Question

This is regarding intermolecular forces.

Which is the only type of intermolecular force present between molecules of hydrogen (H2)? Is it covalent bond, dipole-dipole forces, hydrogen bond, or dispersion forces?

Which of the following is an intermolecular force? Is it covalent bond, ionic bond, metallic bond, or hydrogen bond?

Also, rank these 4 forces in order from weakest to strongest: Disperson forces, Dipole-dipole forces, hydrogen bonds, Chemical bonds

Answer 1

1) dispersion forces also known as london forces are present in non polar molecules. They are instantaneous dipole indice dipole interaction. hence they are weak interactions. In all non polar molecules these interaction are only present.

2) intermolecular forces are present in between 2 different molecules. Hydrogen bond is a type of dipole dipole interaction present in between 2 different molecules. Hence Hydrogen bond is intermolecular forces.

3)strong to weak--- chemical bond > hydrogen bond > dipole dipole > dispersion forces.
