Question
The boiling point of water is 100°C, the boiling point of ethanol is 78°C, and the boiling point of carbon tetrachloride is 76°C. Which describes the strength of the forces between the molecules of water, ethanol, and carbon tetrachloride?(1 point)
Responses

The forces between molecules are greatest for carbon tetrachloride and ethanol molecules but much lower for water molecules.
The forces between the molecules of water, ethanol, and carbon tetrachloride are very similar.
The forces between the molecules of water, ethanol, and carbon tetrachloride are very similar.
The forces between water molecules are greater than those between ethanol and carbon tetrachloride molecules.
The forces between water molecules are greater than those between ethanol and carbon tetrachloride molecules.
The forces between them are not a good predictor of boiling points of different substances.

The correct response is:
**The forces between water molecules are greater than those between ethanol and carbon tetrachloride molecules.**
This is due to the presence of stronger hydrogen bonding in water compared to the weaker dipole-dipole interactions and dispersion forces in ethanol and carbon tetrachloride. The higher boiling point of water indicates stronger intermolecular forces.
