ozonolysis

Question

Ozonolysis of alkenes followed by reduction with Zn/H₂O produces:

RankGuru · Accepted Answer

**Ozonolysis** is a method used to locate the position of double bonds in alkenes.
1. **Ozone Addition**: $O_3$ adds across the double bond to form an unstable **ozonide**.
2. **Reductive Cleavage**: The ozonide is treated with **$Zn$ and $H_2O$**. The zinc prevents the formation of $H_2O_2$ (which would oxidize products to acids).
- The double bond is 'clipped' and replaced by oxygen atoms $(C=O)$.
- Result: Depending on the substitution, **aldehydes** or **ketones** are produced.
