Forces of attraction, or repelling between the molecules of different or similar substances are known as intermolecular forces. They are less strong than covalent and ionic bonds. Examples of intermolecular force include dipole-dipole forces London-dispersion forces.

Concepts and Reason

Attractive forces develop between the nucleus and electrons of two atoms, or molecules, when they approach one another. A change in electron distribution occurs within a molecule. Intermolecular forces refers to interactions between neighboring molecules and atoms.

Fundamentals

London-dispersion forces, which are weak and exhibited all the molecules, are not strong. Hydrogen bonding can be strong and is demonstrated by molecules that have O-H, N-H or F-H bond. The dipole-dipole interactions between molecules with net dipoles are mild and are exhibited by them.

These compounds are:

CH₃COOCH₃ has dispersion forces and dipole-dipole interactions H₂O, NH₃, and C₃H₇OH has hydrogen bonding because of bonds. They also have dipole/dipole interactions as well as dispersion forces. CH₄only dispersion forces exist. This is the order in which intermolecular forces are ranked:

CH₃COOCH₃is therefore dominated by dipole-dipole interactions. Hydrogen bonding is the most common interaction in

. The most common interactions in CH₄are London or dispersion interactions.
