Step 1: Understanding the Concept:
Ozonolysis is a reaction that cleaves carbon-carbon double bonds in alkenes using ozone (\(\text{O}_3\)). The intermediate ozonide is then treated with a reducing agent (typically Zn and water). Step 2: Key Formula or Approach:
General ozonolysis reaction of an alkene:
\[ \text{R}_2\text{C=CHR} \xrightarrow[2. \text{ Zn/H}_2\text{O}]{1. \text{ O}_3} \text{R}_2\text{C=O} + \text{RCHO} \]
Step 3: Detailed Explanation:
Depending on the substitution of the alkene, reductive ozonolysis produces aldehydes and/or ketones.
- A terminal \(\text{=CH}_2\) group yields formaldehyde (\(\text{HCHO}\)).
- An internal \(\text{=CHR}\) group yields an aldehyde (\(\text{RCHO}\)).
- An internal \(\text{=CR}_2\) group yields a ketone (\(\text{R}_2\text{C=O}\)).
Among the given options, 'aldehyde' is a standard primary product. Acids are only produced if an oxidative workup (like \(\text{H}_2\text{O}_2\)) is used. Step 4: Final Answer:
Aldehyde is a correct product.
