Detailed explanation-1: -Van der Waals forces are weak intermolecular forces that are dependent on the distance between atoms or molecules. These forces arise from the interactions between uncharged atoms/molecules.

Detailed explanation-2: -The force of attraction or repulsion between the two atoms when they share a pair of electrons are known as covalent bonding. The covalent compounds are formed by two or more nonmetals atoms.

Detailed explanation-3: -The formation of a chemical bond is a result of net attractive forces which dominate. The energy of that system is lowered and molecule is formed. Otherwise if repulsive forces become dominant no chemical bond will be formed.

Detailed explanation-4: -The atoms in most molecules are held together by strong attractive forces called chemical bonds. These bonds are formed through the interaction of valence electrons of the combining atoms.

Detailed explanation-5: -Van der Waals strain is strain resulting from Van der Waals repulsion when two substituents in a molecule approach each other with a distance less than the sum of their Van der Waals radii. Van der Waals strain is also called Van der Waals repulsion and is related to steric hindrance.
