In an Amide Synthesis reaction between acetic anhydride & an unknown primary amine with aluminum oxide. "1. Why is it essential that no water or alcohols are present during the amide synthesis reaction you performed in lab this week? Acetic anhydride can be quenched simply by washing the reaction mixture with water. Provide the balanced equation for the reaction of acetic anhydride and water below."
An acid anhydride reacts with an alcohol to form one ester and one carboxylic acid. An...
An acid anhydride reacts with an alcohol to form one
ester and one carboxylic acid. An unsymmetrical acid anhydride can
react with alcohol at either carbonyl carbon, so there are two
possible esters and two possible carboxylic acids.
Draw the structures of all possible organic products formed in the following reaction. Do not draw counterions or byproducts. CH3 OH CH3 НАС CH3 CH3 HO So

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...

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...

Treatment of a carboxylic acid with trifluoroacetic anhydride leads to an unsymmetrical anhydride that rapidly reacts with alcohol to give an ester. (CF3CO)20 R'OH + CF3CO2H ROH OR' Using the reaction of acetic acid as an example, propose a structure for the first intermediate in the reaction to form the unsymmetrical anhydride. • You do not have to consider stereochemistry. • Do not include counter-ions, e.g., Na+, I, in your answer. • In cases where there is more than one...
