In Introduction this experiment, we will be performing the aldol condensation reaction. In this reaction, a conjugate base (from an aldehyde/ketone) will add to another carbonyl group. This reaction produces resonance hybrids, a carbanion and an enolate. In this particular experiment, we will be producing dibenzyl acetone, while using benzaldehyde as our reactant/electrophile.

UGA - CHEM 2212 - 234-54
Introduction In this experiment, we will be preparing acetate ester acetylsalicylic acid, also know as aspirin. Acetate esters are prepared by reacting anhydrides with the hydroxyl group of alcohols or phenols. Here, we will be preparing acetylsalicy
UGA - CHEM 2212 - 234-54
Introduction In a Fischer esterfication reaction, an ester is synthesized by an acid catalyzed substitution reaction between an alcohol and a carboxylic acid. The carbonyl oxygen is protonated by the acid catalyst which initiates the nucleophilic att
UGA - CHEM 2212 - 234-54
Introduction In this experiment, we will be performing a Grignard reaction. This reaction is a nucleophilic addition between a Grignard reagent and a carbonyl compound. This is very useful because it can form a carbon-carbon bond. A Grignard reagent
