Explanation / Answer

Why does stearic acid melts at 69 C but linoleic acid melts at 5C?

Stearic acid is a saturated fatty acid which means that a significant amount of energy and high temperature are required to separate the fatty acids and melt the fat. Linoleic acid is polyunsaturated fatty acid, this means less energy is required to separate the molecules, making the melting points of unsaturated fats lower than those of saturated fats.

So, filling the spaces with the appropriate terms:

Because the molecules of a saturated fatty acid (like stearic acid) fit closer together than the molecules of a polyunsaturated fatty acid (like linoleic acid), there are stronger attractions between saturated fatty acid molecules, requiring more energy (higher melting points) to break them apart and from liquid.
