Question

In which of the following processes intermolecular forces are not involved ?
(A) electrolysis of water (H20 → H2 + O2)
(B)condensation
(C) sublimation
(D) vaporisation​​

Answer 1

The correct option is d) Vaporisation.

The process in which intermolecular forces are not involved is d)vaporization.

• In the process of vaporization, the state of the matter is changed but there is no chemical reaction that is involved.
• For example, in the case of water during vapourization the state of water changes from liquid to vapor, but there is no chemical reaction that takes place.
• Whereas in the electrolysis of water, the water molecule which is formed from hydrogen and oxygen gets separated.
• Hence, the correct option is d) Vaporisation.
