**Explanation:**
This question presents a multiple-choice format aimed at testing the understanding of intermolecular forces in polar molecules. Below are the options explained:
- **Van der Waals**: A general term for intermolecular forces, including dipole-dipole, hydrogen bonding, and London dispersion forces.
- **Hydrogen bonding**: A special type of dipole-dipole interaction occurring when hydrogen is bonded to a highly electronegative atom like nitrogen, oxygen, or fluorine.
- **Dipole-Dipole**: Occurs between polar molecules where positive and negative ends of different molecules attract each other.
- **London Dispersion**: Weak forces resulting from temporary shifts in the electron cloud of molecules, present in all molecules, but predominant in non-polar ones.
For polar molecules, the most relevant forces typically include hydrogen bonding and dipole-dipole interactions.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F625b5e03-855a-4d44-85af-54ec1b52cebe%2Fdcaf65be-1440-4c81-af72-73d76e96a435%2Fdmo9o_processed.png&w=3840&q=75)

**Options:**
- [ ] Hydrogen bonding
- [ ] Dipole-Dipole
- [ ] London Dispersion
- [ ] Van der Waals
**Explanation:**
This question addresses the types of intermolecular forces that can exist between nonpolar molecules.
**Intermolecular Forces Details:**
1. **Hydrogen bonding**: This is a strong intermolecular force occurring between polar molecules, specifically between hydrogen and electronegative atoms like nitrogen, oxygen, or fluorine. Since it relies on polarity, it is not applicable to nonpolar molecules.
2. **Dipole-Dipole**: These forces occur between polar molecules due to the attraction between positive and negative charges of the molecules. Nonpolar molecules do not have permanent dipoles, so this does not apply.
3. **London Dispersion**: These are weak forces caused by the random motion of electrons, which create temporary dipoles in the nonpolar molecules. This is the only intermolecular force that can occur between nonpolar molecules.
4. **Van der Waals**: This term is often used to describe multiple types of intermolecular forces, including London Dispersion forces. It is applicable to interactions involving nonpolar molecules.
**Correct Answers:**
- London Dispersion
- Van der Waals (since it includes London Dispersion forces)](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F625b5e03-855a-4d44-85af-54ec1b52cebe%2Fdcaf65be-1440-4c81-af72-73d76e96a435%2Fu1dl6hl_processed.png&w=3840&q=75)
