2. If one were esterifying an expensive alcohol with an expensive carboxylic acid derivative, would it be wiser to use the acid chloride or acid anhydride reagent? Why? 3. Why is so much NaOH used in the extraction? Recall that only four drops (small amount) of sulfuric acid were used as a catalyst. Esters are an important class of organic molecules, which are formally derived from alcohols and carboxylic acids. Esters occur widely in nature and are often an important...

Combinatorial Chemistry: Ester Synthesis In today's lab, you will perform small scale Fischer esterifications to make a variety of esters. H2SO4 R OH + R'OH = ROR Combinatorial chemistry is a term used to describe small scale reactions, where in a large number of different molecules can be made using the same reaction conditions, by varying the reactants. In the case of Fischer esterifications, one can vary the carboxylic acid and keep the alcohol constant or keep the carboxylic acid...

acetic acid is 25 ml and alcohol is 20 ml
The synthesis of an ester by the reaction of a carboxylic with an alcohol is an equilibrium reaction. H - R-OH HO ROH R OR, Recall from general chemistry that, according to Le Caiclista principle, an equilibrium can be shifted toward greater product formation by using an excess of reactant or by removal of a reaction product as it forms. 1. Are any products removed during the reaction period (the...

We made esters from carboxylic acids and alcohol. (for one of them, acetic acid + isopentyl alcohol + couple drops of sulfuric acid). Could someone please explain those. Thank you 1. Consider if we had prepared high molecular weight esters, what problems would this pose regarding our method of analysis 2. We used sulfuric acid as a catalyst, but carboxylic acids are a reagent in this reaction. Would simply using excess carboxylic acid work as efficiently as sulfuric acid to...
