4. The ester you drew in Question #1 has a melting point range of 32-35 °C. The methyl ester of mono-unsaturated
palmitoleic acid (IUPAC name: hexadec-9enoic acid) has a considerably lower melting point range: -0.5-+0.5 °C.
a) Explain what it means for a fatty acid to the "mono-unsaturated."
b) Illustrate your explanation by drawing the structure of the methyl ester of octadec-11-enoic acid. (Be sure to draw
the geometric stereoisomer that is commonly found in nature.)
Indicate whether each statement is true or false: (a) Trans fats are saturated. (b) Fatty acids are long-chain carboxylic acids. (c) Monounsaturated fatty acids have one CC single bond in the chain, while the rest are double or triple bonds.
