(a)

Interpretation Introduction

Interpretation:

Structural formula for the saponification acidification and decarboxylation product of β-ketoester diethyl 2-methyl-3-oxosuccinate has to be drawn.

Concept Introduction:

Saponification:

It is a process in which triglycerides reacts with sodium or potassium hydroxide to form fatty acids and glycerol.  This reaction is also known as alkaline hydrolysis of ester.

Decarboxylation:

It is a reaction which involves the release of carbondioxide by removing the carboxyl group.  This also involves the removal of carbon atom from the chain.

(b)

Interpretation Introduction

Interpretation:

Structural formula for the saponification acidification and decarboxylation product of β-ketoester ethyl 2-methyl-3-oxo-3-phenylpropanoate has to be drawn.

Concept Introduction:

Saponification:

It is a process in which triglycerides reacts with sodium or potassium hydroxide to form fatty acids and glycerol.  This reaction is also known as alkaline hydrolysis of ester.  Saponification is mainly used for manufacturing soap.

Decarboxylation:

It is a reaction which involves the release of carbondioxide by removing the carboxyl group.  This also involes the removal of carbon atom from the carbonchain.  Enzymes which catalyze decarboxylation are known as decarboxylase.  Alkanoic acid decarboxylation is very slow.

(c)

Interpretation Introduction

Interpretation:

Structural formula for the saponification acidification and decarboxylation product of ethyl 2-methyl-3-oxopropanoate has to be drawn.

Concept Introduction:

Saponification:

It is a process in which triglycerides reacts with sodium or potassium hydroxide to form fatty acids and glycerol.  In simple saponification is a reaction between an acid and a base to form salt.  The base commonly used is sodium hydroxide.  Potassium hydroxide is also used.  This reaction is also known as alkaline hydrolysis of ester.

Decarboxylation:

It is a reaction which erases a carbon atom from the carbon chain by releasing carbondioxide.  It is a unimolecular dissociative process that gives a carbanion and carbondioxide.

Ethyl butyrate, CH3CH2CH2CO2CH2CH3CH3CH2CH2CO2CH2CH3, is an artificial fruit flavor commonly used in the food industry for such flavors as orange and pineapple.  Its fragrance and taste are often associated with fresh orange juice, and thus it is most commonly used as orange flavoring. It can be produced by the reaction of butanoic acid with ethanol in the presence of an acid catalyst (H+H+): CH3CH2CH2CO2H(l)+CH2CH3OH(l)H+⟶CH3CH2CH2CO2CH2CH3(l)+H2O(l) Part A Given 7.30 gg of butanoic acid and excess ethanol, how many grams of ethyl butyrate would be synthesized, assuming a complete 100%% yield? Express your answer in grams to three significant figures.   Part B A chemist ran the reaction and obtained 5.95 gg  of ethyl butyrate. What was the percent yield? Express your answer as a percent to three significant figures.   Part C The chemist discovers a more efficient catalyst that can produce ethyl butyrate with a 78.0%% yield. How many grams would be produced from 7.30 gg of…
