Arrange the following substances in increasing order of forces of attraction.

• A. Oxygen, water, sugar
• B. Sugar, water, oxygen
• C. Water, sugar, oxygen
• D. Sugar, oxygen, water

To arrange the substances in increasing order of forces of attraction, we need to consider the types of intermolecular forces present in each substance.

Substance Overview

• Oxygen (O₂): A nonpolar molecule with weak London dispersion forces.
• Water (H₂O): A polar molecule with strong hydrogen bonding.
• Sugar (C₆H₁₂O₆): A polar molecule with significant hydrogen bonding, similar to water.

Forces of Attraction

The forces of attraction can be ranked based on their strength:

• Oxygen has the weakest forces (London dispersion).
• Water has stronger forces due to hydrogen bonding.
• Sugar has similar strong hydrogen bonding, but it can be slightly stronger than water due to its larger size and more extensive hydrogen bonding capabilities.

Increasing Order of Forces

Based on this analysis, the correct increasing order of forces of attraction is:

Oxygen, Water, Sugar

Thus, the answer is option A: Oxygen, water, sugar.
