Which of the following 18 carbon fatty acids will have the lowest melting point?
A) oleic acid
B) linoleic acid
C) linolenic acid
D) stearic acid

Question

Quizplus · Accepted Answer

Linolenic acid has three double bonds in its chain, making it more unsaturated than oleic acid (one double bond) and linoleic acid (two double bonds). The presence of double bonds creates kinks in the fatty acid chain, which prevent tight packing and increase fluidity, lowering the melting point. Stearic acid, on the other hand, is a saturated fatty acid with no double bonds and a higher melting point.
