Intermolecular forces are forces of attraction and repulsion between interacting paiticles that will include :
A. dipole - dipole forces. B. dipole - induced dipole forces. C. hydrogen bonding. D. covalent bonding. E. dispersion forces. Choose the most appropriate answer from the options given below :
Intermolecular forces are forces of attraction and repulsion between interacting paiticles that will include :
A, B, C, D are correct.
A, B, C, E are correct.
A, C, D, E are correct.
B, C, D, E are correct.
The Correct Option is B
Solution and Explanation
When two or more molecules are attracted to one another, this is known as intermolecular forces.
Dipole-dipole attraction occurs when two or more polar molecules come into contact.
Dipole-induced dipole (attraction of polar and nonpolar molecules).
Dipole-dipole and ion-dipole attraction have a unique form called hydrogen bonding.
Dispersion forces (which primarily function between non-polar molecules).
Covalent bonds (which take place between atoms rather than between molecules).
Therefore, The correct option is (B): A, B, C, E are correct.

States of Matter
The matter is made up of very tiny particles and these particles are so small that we cannot see them with naked eyes.
There are three States of Matter:
The three states of matter are as follows:
Solid State:
- The solid-state is one of the fundamental states of matter.
- Solids differ from liquids and gases by the characteristic of rigidity.
- The molecules of solids are tightly packed because of strong intermolecular forces; they only oscillate about their mean positions.
Liquid State:
- The molecules in a liquid are closely packed due to weak intermolecular forces.
- These forces are weaker than solids but stronger than that of gases.
- There is much space in between the molecules of liquids which makes their flowing ability easy.
Gaseous State:
- In this state of matter, distances between the molecules are large (intermolecular distance is in the range of 10-7-10-5 cm.
- The intermolecular forces experienced between them are negligible.
- Thus, translatory, rotatory and vibratory motions are observed prominently in gases.
