(a)
Interpretation:
Whether the saturated fatty acid typifies as a fat, an oil, or both is to be stated.
Concept introduction:
A lipid is a compound which is made up of an alcohol and one or more carboxylic acids. Lipids are found in fats and vegetable oils. Fats and oil are formed by the esters of glycerol. Fatty acids are the triglycerides formed from the reaction between three long chain carboxylic acids and glycerol joined by three ester linkages.

- Determine if the following salt is neutral, acidic or basic. If acidic or basic, write the appropriate equilibrium equation for the acid or base that exists when the salt is dissolved in aqueous solution. If neutral, simply write only NR.

Next, record any regiochemistry or stereochemistry considerations relevant to the reaction. You should also record any key aspects of the mechanism, such as forma- tion of an important intermediate, as a helpful reminder. You may want to keep track of all reactions that make carbon-carbon bonds, because these help you build large molecules from smaller fragments.
