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.♦ Relevant knowledge
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.
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.
CH4 only dispersion forces exist.
This is the order in which intermolecular forces are ranked:
CH3COOCH3 is therefore dominated by dipole-dipole interactions.
Hydrogen bonding is the most common interaction in
.
The most common interactions in CH4 are London or dispersion interactions.
