Intermolecular Forces

In chemistry, intermolecular interactions are molecular interactions between neighbouring molecules, governed by attractive and repulsive forces. 

An acid is like a sour superhero, let’s call him Acidus, that loves to give away tiny pieces called protons (or H⁺ pieces). The stronger he is, the more protons he can donate as H⁺.

Intermolecular forces are collective forces in organic chemistry that cause atoms and molecules to stick together and interact; therefore, they are electrostatic in natur

London Dispersion, a type of Vander Waal Force, is the weakest of the three types, yet, it is the only one universally present in all the atoms and molec

Vander Waals is an attractive universal force that operates when the atoms and molecules are within a distance range of 0.4- 0.6 nm.

Dipole-dipole interactions occur in polar molecules where the difference in electronegativity between the combining atoms creates positive and negative dipoles.

Among the various types of solids—metallic, ionic, and covalent—the molecular solid stands out for its intermolecular attractive strength.

Van der Waal’s interactions are the weak intermolecular forces of interactions.

Debye intermolecular forces of attraction occur between polar and nonpolar atoms or molecules.

Debye intermolecular forces of attraction occur between polar and nonpolar atoms or molecules.

If the size of a nonpolar atom is greater, it means that the atom has a higher number of electron containing orbitals.

Debye interactions require polar molecules to show polar-nonpolar type of intermolecular attractive interactions.

The strength of polar-nonpolar interactions is affected by the atomic size of the nonpolar atom (or molecule) and the electronegativity of the polar molecule. 

A polar molecule has natural poles. Therefore, when next to a nonpolar molecule, it will try to magnetize it temporarily. 

London dispersion forces are the weak intermolecular attractive forces that occur when the molecules are spaced closely.

London dispersion forces are the weak intermolecular forces that occur when the molecules are in close proximity to each other.

London dispersion forces are weak intermolecular forces found in all atoms and molecules.

London Dispersion forces are seen in all the atoms and the molecules; however, it is the exclusive force binding nonpolar molecules.

All atoms and molecules show London Dispersion Force, a primary way atoms and molecules interact.

A nonpolar molecule is made of two or more atoms where the electronegativity difference between the atoms is less than 0.5.

London dispersion force is the weakest of the three van Der

Polar molecules show Keesom forces.

A molecule is said to be polar if the bond electrons between the atoms in a covalent bond are unequally distributed, creating two ends.
