Vedclass · Answer

(B) The reaction of $but-2-ene$ $(CH_3-CH=CH-CH_3)$ with $O_3$ followed by reductive workup with $Zn / H_2O$ is known as reductive ozonolysis.In this reaction,the double bond is cleaved to form two molecules of acetaldehyde $(CH_3CHO)$.The reaction mechanism is as follows:$CH_3-CH=CH-CH_3 + O_3 ightarrow 	ext{Ozonide intermediate}$$	ext{Ozonide} + Zn / H_2O ightarrow 2CH_3CHO + ZnO + H_2O$Therefore,the major product is acetaldehyde $(CH_3CHO)$.

The major product formed when $but-2-ene$ is reacted with $O_3$ followed by treatment with $Zn / H_2O$ is:
