OH H+ CH3 H3C OH Esters can be synthesized by an acid-catalyzed nucleophilic acyl substitution between an alcohol and a carboxylic acid; this process is called the Fischer esterification reaction. Because the alcohol oxygen is a poor nucleophile, the carbonyl carbon is made a better electrophile by protonation of the carbonyl oxygen. The steps of the synthesis are all reversible. The reaction is generally driven to completion by using an excess of the liquid alcohol as a solvent, or by...

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.

The primary structure of a protein is formed by the condensation of amino acids in a certain sequence. Consider the dipeptide formed by the condensation of glycine and tyrosine in Figure 8.31B. a. Draw the structure of the dipeptide that would be formed if the two amino acids condensed in the opposite sequence. b. How are the structures of the dipeptides in Figure 8.31B and your drawing related to each other? B 0 HN-C-0--OH HO H-N-C-C-OH H CHE H OH...

True or false (encircle as appropriate). 1. 5% NaHCO3 solution differentiates between a carboxylic acid and an alcohol. True / false 2. Beilstein flame test is meant to determine whether the compound is aromatic. True / False 3. Lucas reagent is a mixture of zinc chloride and hydrochloric acid True / False 4. Black soot is obtained when you burn a non-aromatic compound in open flame. True / False 5. Esters react with hydroxylamine hydrochloride under basic conditions. True False

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...
