Chapter 21, Problem 31P
Interpretation Introduction

Interpretation:

The structural formula for the enol form of diethyl malonate has to be drawn, the structural formulas for three enols of ethyl acetoacetate have to be drawn, among them, the most and least stable isomer has to be identified and the products of the reaction of bromine with both diethyl malonate and ethyl acetoacetate are to be stated.

Concept introduction:

Enol refers to an intermediate structure that consists of an alkene group attached with a hydroxyl group at one end of its double bond.

The percentage of enol in keto-enol tautomerism depends upon the stability of enol formed.

The odor of ripe bananas and many other fruits is due to the presence of esters. For example: Banana oil (isopentyl acetate)     (a) Write the name (common or IUPAC) of the ester responsible for the fragrance of the following: pineapple, orange, apple, peach, & lavender     (b) Choose one fragrant from (a) and name the alcohol and the carboxylic acid needed to synthesize this ester.     (c) Show the detailed mechanism of the Fischer Esterification reaction that will be involved in the synthesis of the fragrant you have chosen in part (a).
4) Give an example of an enol which would tautomerize into a) an aldehyde and b) a ketone.
Draw the structural formula of the enol formed in each alkyne hydration reaction; then draw the structural formula of the carbonyl compound with which each enol is in equilibrium
