Question

Which of the following substances exhibit the strongest intermolecular attractive forces?

• A. Water
• B. Ethanol
• C. CO₂
• D. Sugars

Answer 1

The correct option is D

Sugars

Solid — A substance that has fixed volume and fixed shape & size

• It has high intermolecular forces
• It has low intermolecular space
• They possess low kinetic energy
• for example — sugar, table, stone, etc

Liquid — A substance that has fixed volume but no fixed shape & size

• It has moderate intermolecular forces
• It has moderate intermolecular space
• They possess moderate kinetic energy
• for example — water, ethanol, cold drinks, etc

Gas — A substance that has neither fixed volume nor fixed shape & size

• It has low intermolecular forces
• It has high intermolecular space
• They possess high kinetic energy
• for example — CO₂, O₂, etc

Thus, opotion D is correct I:e Sugars
