Which of the following option is correct about Van Der Waal's force
1. Non directional
2. Weak
3. Both 1 and 2
4. None of the above
Answers
Answer:
Option 3 is the correct answer.
Explanation:
Information about Van Der Waal force
1. These are the weak forces.
2. These are non directional.
3. Non valence of attraction among neutral species.
4. Electrical in nature because of induced polarity occurred by the temporary displacement of the e- towards one inert atom's end.
5. Ease of distortion of electron cloud is the basis of strength of the Van Der Waal force.
6. Melting point and Boiling point increases down the group.
Van der waals force is non directional as well as weak.
So answer should be option 3). Both 1 and 2.

★ The attraction of intermolecular forces between the molecule can be termed as van der waals forces.
★ It can be also called London dispersion force as it is weak in nature.
★ There are three types of van der waals forces :
- dispersion
- dipole - dipole
- hydrogen
★ Example of van der waals forces is hydrogen bonding.
