Chapter 21, Problem 21.82P

Interpretation Introduction

Interpretation:

Complete and detail mechanism for the given reaction is to determined.

Concept introduction:

In nucleophilic addition reaction nucleophile is attack on most electrophilic carbon atom results in the formation of new bond between nucleophile and electrophilic carbon atom.

In case of proton transfer reaction proton is abstracted by the electronegative atom like oxygen, nitrogen etc.

Heterolysis is the removal of water.

In case of nucleophile elimination, good leaving group is expelled to reform the carbonyl bond.

In intra molecular acid-catalyzed transesterification reaction one ester is transformed into another ester and ring formation takes place.
