Question 1:

Which of the following intermolecular forces is responsible for the high boiling point of water?

Explanation: The high boiling point of water is primarily due to hydrogen bonding, which is a strong intermolecular force. Hydrogen bonding occurs between the hydrogen atom of one water molecule and the oxygen atom of another water molecule, resulting in the formation of a network of hydrogen bonds.

Question 2:

Which intermolecular force is responsible for the viscosity of syrup?

Explanation: The viscosity of syrup is primarily due to the presence of large, complex molecules that experience strong intermolecular forces, such as van der Waals forces. Van der Waals forces include London dispersion forces and dipole-dipole interactions, which play a role in the viscosity of syrup.

Question 3:

Which intermolecular force is the weakest?

Explanation: London dispersion forces, also known as induced dipole-induced dipole forces, are the weakest intermolecular forces. They occur between all molecules, regardless of polarity, and are caused by temporary fluctuations in electron distribution.

Question 4:

Which intermolecular force is responsible for the surface tension of water?

Explanation: The surface tension of water is primarily due to hydrogen bonding. Hydrogen bonds between water molecules create a cohesive force that resists the disruption of the water surface, resulting in high surface tension.

Question 5:

Which intermolecular force is present in all molecules?

Explanation: London dispersion forces, also known as van der Waals forces, are present in all molecules. They arise from temporary fluctuations in electron distribution and contribute to intermolecular attractions, even in nonpolar molecules.
