Linkages named for this functional group join the monomers of the 3D printing filament PLA. Compounds with this functional group and acyl (“ace-ill”) chlorides react with [emphasize] two equivalents of Grignard reagent to form tertiary alcohols. Cyclic varieties of these compounds are known as (-5[1])lactones. (10[1]-5[1])Examples of these compounds such as triglycerides can be hydrolysed with sodium hydroxide in (0[1]-5[1])saponification. Names of (-5[1])these (-5[1])compounds feature the suffix (-5[2])“-oate,” (“oh-ate”) as in methyl propanoate (10[1])(“pro-PAN-oh-ate”). In a reaction named for Emil Fischer, these compounds are synthesized by (10[1])refluxing an alcohol with a carboxylic acid. For 10 points, an R-C-O-O-R’(“R-C-O-O-R-prime”) group (10[1])characterizes what fruit-scented compounds? ■END■ (10[2]0[3])
