If you attempted to make soap from butanoic acid by forming sodium butanoate, would your preparation have the properties to act as an emulsifying agent (soap)?

Discuss the preparation and properties of phenol

Chapter 1 (Carbonyl compounds I) Explain how the class I carbonyl compound reacts? What will be the product when ethylamine and propyl amine reacts with acetyl chloride? Why only one amide obtained after the reaction of acetyl chloride with a mixture of ethylamine and trimethylamine? Excess amine is required in the reaction of acetyl chloride with amine whereas excess alcohol is not required in the reaction of acetyl chloride and alcohol. Why? List the following ester in order of decreasing reactivities towards hydrolysis with reason: Methyl benzoate, p-nitro methyl benzoate and p-methoxy methyl benzoate The reaction of an ester with an amine is not as slow as the reaction of an ester with water or an alcohol. Explain with reason. Explain why the rate of aminolysis of an ester cannot be increased by H+, OH- or OR-. How can you activate the carboxylic acid? Is acid catalyzed hydrolysis of acetamide a reversible or an irreversible reaction. Explain. Chapter 2 (Carbonyl compounds II)…

The flavors and aromas of almost any fruit are primarily due to esters. In an experiment, an artificial fruit flavor is prepared using the Fischer esterification (reaction of an alcohol with a carboxylic acid in the presence of sulfuric acid catalyst). Why is sodium bicarbonate solution used in the workup of the reaction? What advantage does sodium bicarbonate have over sodium hydroxide solution?

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.

3B. Will phenyl magnesium bromide react with formic acid to form an ester? If so, write the reaction. If not, explain why.

Write the synthesis of phenyl benzoate, aspirin and isoamyl acetate with the reaction equations and name the starting materials.

Show a reaction how ester methyl stearate can be used to make soap.

What is the equation for the dissociation of a carboxylic acid in water?

1. Write a balanced chemical equation to show the dissociation of Butanoic acid (C3H7COOH). Physical states must be included. 2. When butanoic acid (C3H7COOH) reacts with the strong base potassium hydroxide (KOH), potassium butanoate (C3H7COOK), a salt of the weak acid is formed. Write a balanced chemical equation to show the dissociation of the potassium butanoate (C3H7COOK). Physical states must be included.
