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. (-5[1])Examples of these compounds such as triglycerides can be (-5[1])hydrolysed with sodium hydroxide in (10[1]-5[1])saponification. Names of these compounds feature the suffix “-oate,” (“oh-ate”) as (-5[1])in methyl propanoate (“pro-PAN-oh-ate”). In a reaction (-5[1])named for Emil (10[1])Fischer, these compounds are (10[2])synthesized by refluxing an alcohol with a carboxylic acid. For 10 points, an R-C-O-O-R’(“R-C-O-O-R-prime”) group characterizes what fruit-scented compounds? (10[2])■END■ (10[1]0[1])
