Quizplus · Accepted Answer

The melting point of fatty acids increases with the length of the carbon chain and decreases with the presence of double bonds (unsaturation). The given fatty acids are ordered from the one with the most double bonds (lowest melting point) to the one with the least double bonds (highest melting point), reflecting their increasing melting points.
