Question
Chapter 21, Problem 45P
Interpretation Introduction
Interpretation:
The formation of the product if each of the given reactants undergoes Claisen condensation is to be explained.
Concept Introduction:
Claisen condensation occurs between two esters or one ester and a carbonyl compound that must have an alpha hydrogen atom with them
It favours the formation of a single bond between two carbon atoms in the presence of a strong base.
The product formed ion the Claisen condensation is either a
