Unsaturated fatty acids tend to be liquid at room temperature, while saturated fatty acids are usually solid at room temperature. The explanation for this difference is that

A. saturated fatty acids have a rigid structure that allows them to pack densely, making them solid at room temperature.
B. unsaturated fatty acids are usually short-chain fatty acids and therefore are usually oils.
C. double bonds are stabilized at room temperature, resulting in oil formation.
D. double bonds are destabilized at room temperature, resulting in more random movement of fatty acids in oils.

Question 2

Short-chain fatty acids are usually liquid at room temperature while long-chain fatty acids are usually solid at room temperature. The explanation for this difference is that

A. chain length affects the temperature at which a fatty acid melts.
B. chain length affects water solubility.
C. chain length is modified by room temperature.
D. short-chain fatty acids generally have more double bonds than long-chain fatty acids.
