D) stearic acid

Question

Quizplus · Accepted Answer

Stearic acid has no carbon-carbon double bonds (it is a saturated fatty acid), which means it can pack together more tightly in a solid state, resulting in a higher melting point compared to the other fatty acids listed which all have at least one double bond. Double bonds create kinks in the fatty acid molecule, preventing tight packing and resulting in a lower melting point.
