Answer 2

Answer:

(D) vaporization​

vaporization is a process in which no intermolecular forces are involved.

Explanation:

Ionic bonding is stronger than any of the intermolecular forces listed, but it is NOT an intermolecular force in and of itself. Intermolecular forces are a more transient and temporary attraction between independent molecules, whereas ionic bonds are a permanent chemical connection between two atoms. The state of matter is changed during the vaporization process, but no chemical reaction occurs.

For example: during vaporization of water, the state of water changes from liquid to vapor, but no chemical reaction occurs. In contrast, water molecules formed from hydrogen and oxygen are separated during electrolysis.

As a result, the correct answer is d) Vaporization.
