uestion 35 3 points What is the role of H2SO4 in the following reaction? H2SO4 OH OH It is a base catalyst that deprotonates the carboxylic acid making it more nucleophilic. Its an acid catalyst that protonates the alcohol O making the alcohol more electrophilic. It is an acid catalyst that protonates the carbonyl oxygen making the carbonyl carbon more electrophilic It is a base catalyst that deprotonates the alcohol to make it more nucleophilic.

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.

Esterification is the reaction of a carboxylic acid (RCOOH) with an alcohol (R'OH) to form an...
Esterification is the reaction of a carboxylic acid (RCOOH) with an alcohol (R'OH) to form an ester (RCOOR') with loss of water. Equation [1] is an example of an intermolecular esterification reaction. Equation [2] is an example of an intramolecular esterification reaction, that is, the carboxylic acid and alcohol are contained in the same starting material, forming a cyclic ester as product. The equilibrium constants for both reactions are given. Explain why K is different for these two apparently similar...
