Question
**Question:** As the size of a molecule increases, London Dispersion Forces increase. - ○ True - ○ False **Explanation:** This is a question assessing the understanding of intermolecular forces, specifically London Dispersion Forces. - **London Dispersion Forces** are a type of weak intermolecular force that occur due to the momentary distribution of electron density in a molecule, which creates a temporary dipole. - These forces are present in all molecular interactions, but they are more significant in larger molecules because larger molecules have more electrons, which can contribute to stronger temporary dipoles. - Hence, as the size and surface area of the molecule increase, the London Dispersion Forces also generally increase. **Answer Choice Descriptions:** - **True:** Select this option if you agree with the statement that increasing molecular size results in stronger London Dispersion Forces. - **False:** Select this option if you disagree with the statement.

Expert Solution
Step 1

All the non-polar molecules have London-dispersion force of interaction.

As the molecular size increases then molecular weight also increases.
