It forms an intermediate sulfonate ester intermediate which is attacked by the alcohol to produce product. It catalyzes the reaction by protonating the carboxylic acid, making it more susceptible to attack by the alcohol b nucleophile. It forms a sulfonate ester, converting the alcohol into a good leaving group, thereby speeding up the reaction. C It protonates the alcohol functional group, causing water to leave the molecule. The resulting carbocation attacks the carboxylic acid. Resul

Isoamyl Acetate Synthesis One method to promote the formation of the ester is to add an excess of acetic acid. Suggest another method to shift the reaction toward ester formation.
Upon completion of a chemical reaction, you find you have a mixture of benzoic acid and ethyl benzoate. Propose a procedure to separate the ethyl benzoate from the mixture. You should look up the structures of benzoic acid and ethyl benzoate.
On synthesis of esters via nucleophilic acyl substitution: Write the chemical equation involved in the reaction between the excess acid and NaHCO3. Given this, briefly explain why NaHCO3 is preferred over NaOH for the neutralization of excess acid. Also, explain how excess alcohol was eliminated from the crude product.
What is the role of the acetic acid in the oxidation of Cyclohexanol to Cyclohexanone? Write the balanced chemical reaction between acetic acid and sodium hypochlorite.
a) Esters can be cleaved back into a carboxylic acid and an alcohol by reaction with water and a base. The reaction is called a saponification from the Latin sapo which means soap. The name comes from the fact that soap used to be made by the ester hydrolysis of fats. Due to the basic conditions a carboxylate ion is made rather than a carboxylic acid. i) Write the reactions of saponification ii) Write the reaction of saponification mechanism of the reaction.
Use the carboxylic acid and alcohol listed below to make an ester using a Fischer esterification. Draw a reaction scheme (like on the top of each page in the manual) to show which starting materials and reagents you would use, and name the product using proper nomenclature.

1) Nitriles are typically hydrolyzed to form what class of compounds? 2) what must one keep in mind when performing the hydrolysis of a nitrile to a carboxylic acid? 3) why are nitriles over-looked as carboxylic acid derivatives?
Give the name (common name or IUPAC name) of intermediate product (a) in the following reaction.
Aldehydes and ketones react with one molecule of an alcohol to form compounds called hemiacetals, in which there is one hydroxyl group and one ether-like group. Reaction of a hemiacetal with a second molecule of alcohol gives an acetal and a molecule of water. We study this reaction in Chapter 16. Draw structural formulas for the hemiacetal and acetal formed from these reagents. The stoichiometry of each reaction is given in the problem.
