Which statement is TRUE about fatty acids?

Question

Quizplus · Accepted Answer

Fatty acids with longer chains have a higher melting point because it takes more energy to break the bonds between the molecules. Additionally, fatty acids with longer chains have lower solubility in water because water molecules are polar and cannot easily interact with nonpolar fatty acid chains. However, the number of double bonds in a fatty acid affects its degree of unsaturation, which affects its melting point in a more complicated way. Fatty acids with more double bonds have lower melting points because the kinks caused by the double bonds prevent the molecules from packing tightly together, which makes it easier to break the bonds between them.
