Interpretation Introduction

Interpretation: A stepwise mechanism for the conversion of $\text{heptane}-2,6-\text{dione}$ into $3-\text{methylcyclohex}-2-\text{enone}$ with the help of $\text{NaOEt}$, $\text{EtOH}$ is to be drawn.

Concept Introduction: Aldol reaction is the condensation reaction of the organic chemistry. In this reaction an enolate ion or an enol reacts with the carbonyl compound that leads to the formation of $\text{β}$-hydroxyaldehyde or $\text{β}$-hydroxyketone which on further dehydration gives the conjugated enone.

The aldol reaction that takes place within the same molecule in the presence of strong base is known as intramolecular aldol reactions. This reaction generally takes place within the dicarbonyl compounds in which one carbonyl group forms the enolate ion that acts as a nucleophile and the carbonyl carbon of the second carbonyl group acts as an electrophile.
