Question

Fats have only saturated fatty acids and are ________ at room temperature due to ________ melting points. Oils have unsaturated fatty acids and are ________ at room temperature due to ________ melting points.

Answer 1

Answer: The correct answer is : solid, high; liquids, low

Explanation: Saturated fatty acids have higher melting points because they have strong dispersion forces between long carbon chains. A significant amount of energy is needed to separate or melt the fatty acid. As the length of the Carbon chain increases, more interactions occur between C chain, requiring higher melting points.
