question 19

Multiple Choice

A solution of chloroform, CHCl₃, and acetone, (CH₃) ₂CO, exhibits a negative deviation from Raoult's law. This result implies that

• A) chloroform-chloroform interactions are stronger than chloroform-acetone interactions.
• B) chloroform-chloroform interactions are weaker than chloroform-acetone interactions.
• C) acetone-acetone interactions are stronger than chloroform-acetone interactions.
• D) acetone-acetone interactions are weaker than chloroform-acetone interactions.
• E) Both B and D.
• F) Both A and C.

Definitions:

Osmosis

The movement of water molecules through a semipermeable membrane from a region of lower solute concentration to one of higher concentration.

Charged Molecules

Molecules that have an electric charge due to the loss or gain of one or more electrons.

Lipid Molecules

Organic molecules that are fatty acids or derivatives, insoluble in water but soluble in organic solvents, playing key roles in energy storage, structure, and signaling.

Permeability

A measure of the ability of a material to allow fluids or gases to pass through it.
