Interpretation Introduction

(a)

Interpretation: The alkyne which yields the given oxidative cleavage products is to be predicted.

Concept introduction: In presence of ozone and ${\text{H}}_{\text{2}}\text{O}$, oxidative cleavage occurs in alkynes. In oxidative cleavage both the sigma and pi bonds of the alkyne is broken. In case of terminal alkynes, carboxylic acid and carbon dioxide is formed while in case of internal alkynes, only carboxylic acids are formed.
