Question

Fats that contain ____ double bonds are liquids at room temperature, whereas fats that contain ____ double bonds are solids at room temperature.​
A) ​trans; cis
B) ​cis; trans
C) ​hydrogenated; partially hydrogenated
D) ​partially hydrogenated; hydrogenated
E) ​unsaturated; saturated

Quizplus · Accepted Answer

Fats that contain unsaturated double bonds (which can include cis or trans configurations, but in this context, unsaturated typically implies cis double bonds) are generally liquids at room temperature because the kinks in their chains prevent them from packing closely together. Fats that contain saturated bonds (no double bonds) are solids at room temperature because they can pack closely together without any kinks, allowing for stronger intermolecular forces.
