Round 5: Tossup 2

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 lactones. Examples of these compounds (10[1])such as triglycerides (-5[1])can be hydrolysed with sodium hydroxide in saponification. Names of these compounds feature the suffix “-oate,” (“oh-ate”) as in methyl propanoate (-5[1])(“pro-PAN-oh-ate”). In a reaction named for Emil Fischer, these compounds are synthesized by refluxing an alcohol with a carboxylic acid. (10[1])For 10 points, an R-C-O-O-R’(“R-C-O-O-R-prime”) group (10[1]-5[1])characterizes what fruit-scented compounds? ■END■
