Chapter 18, Problem 18.21P
Interpretation Introduction

Interpretation:

Way in which the given observation bears on the formation of a terahedral carbonyl addition intermediate during acid-catalysed easter hydrolyis, the corresponding transformation has to be shown.

Concept Introduction:

Transesterification is the process of formation of a new ester molecule from the reaction of alcohol and an ester. This is like hydrolysis of ester but here nucleophile is alcohol molecule instead of H2O. As alkoxide groups have same basicity, therefore, an excess amount of alcohol is used. The addition of an acid also increases the rate of reaction by protonating the carbonyl oxygen atom. A general transesterification is  written as,

Many multi-step organic reaction mechanisms involve proton transfer steps. For example, the first step of Fischer esterification of carboxylic acids(as shown with acedic acid) is activation of the acid by protonation. Based on your understanding of which reaction pathway is more favorable, explain why using chemical structures.
Under milder temperatures than what is needed for dehydration, strong acids catalyze the self-condensation of 1-propyl alcohol to give di-n-propyl ether. The mechanism differs from that of today's reaction in that the protonated alcohol undergoes an Sn2 rather than an Sn1 reaction. Write the mechanism for the acid catalyzed condensation of ethyl alcohol to give diethyl ether. Make sure the mechanism includes protonation, Sn2, and deprotonation.
1. Aromatic compounds are metabolized via transformation of the aromatic ring to a reactive metabolite, arene oxide. Suggest two possible reactions of this metabolite and provide the products of those reactions ? P450 aromatic arene ? compound oxide ?
