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 tu te "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.)

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.)
