Students create a library of carboxylic acids by using differentially substituted, commercially available aryl bromides, which can be used as the starting materials for a multistep synthesis. This is a modification and improvement of a very popular undergraduate organic chemistry experiment.en-USAttribution Non-Commercial Share-Alike 3.0 Unportedhttp://creativecommons.org/licenses/by-nc-sa/3.0/Organomagnesium reagentSeparationLibrary of carboxylic acidsGrignard reactionBenzoic acidDry iceInfrared spectroscopy (IR)Nuclear magnetic resonance spectroscopy (NMR)Liquid-liquid extractionUse of dry glasswareCarbon dioxideNucleophilic addition to carbonylVacuum filtration
