Chapter 21, Problem 21.13P

Interpretation Introduction

Interpretation: The alkene that would yield $\text{2, 2-dimethoxycyclopentane-1, 3-dicarbaldehyde}$ on treatment with ${\text{O}}_{\text{3}}$ followed by ${\left({\text{CH}}_{\text{3}}\right)}_2\text{S}$ is to be identified.

Concept introduction: Alkene yields dicarbonyl compounds, when they are treated with ${\text{O}}_{\text{3}}$ followed by ${\left({\text{CH}}_{\text{3}}\right)}_2\text{S}$ at low temperature. This reaction is known as ozonolysis. The reaction involves cleavage of $\text{C}=\text{C}$ bond, and conversion of it into two $\text{C}=\text{O}$ bonds.
