The given R groups of fatty acids are to be classified as saturated and unsaturated, and the molecules forming solid fats are to be identified. Concept Introduction: Triglycerides are formed by the combination of glycerol and three fatty acids. Triglycerides have three long hydrocarbon chains. The hydrocarbon chain contains between 7 and 21 carbon atoms. They are nonpolar and immiscible with water. The fats which do not contain double bonds in their hydrocarbon chains and are solid at room temperature are known as saturated fats. Unsaturated fats are the ones whose hydrocarbon chains contain one or more double bonds and are in the liquid state at room temperature.

For the compound: C8H17NO2 Use the following information to come up with a plausible structure: 8 This compound has "carboxylic acid amide" and ether functional groups. The peaks at 1.2ppm are two signals that are overlapping one another. One of the two signals is a doublet that represents 6 hydrogens; the other signal is a quartet that represents 3 hydrogens.
