Question

Question: Draw the products formed when each naturally occurring compound is treated with ${\mathit{O}}_{\mathbf{3}}$followed by Zn,${\mathit{H}}_{\mathbf{2}}\mathit{O}$.

Short answer

Answer

a.

b.

c.

Step-by-step solution

Ozonolysis of alkene

It is done by ozone, followed by Zn,${\mathit{H}}_{\mathbf{2}}\mathit{O}$. It involves the formation of aldehyde and ketone by breaking ozonide.

Identification of products in a, b and c

a. The reaction of squalene with $O_3$, followed by Zn, $H_{2}O$ is shown below:

b. The reaction of linolenic acid with $O_3$, followed by Zn, $H_{2}O$ is shown below:

Product formation in b

c. The reaction of zingiberene with $O_3$, followed by Zn, $H_{2}O$ is shown below:
