Using an aldol condensation reaction. He found a few cyclic alkenes in his laboratory. He thought of performing ozonolysis reaction on the alkene to produce a dicarbonyl compound followed by aldol reaction to prepare "x". Predict the suitable alkene that can lead to the formation of "x".
Show Hint
In ozonolysis, the alkene is cleaved to form two carbonyl-containing compounds, which can then undergo aldol condensation to form alpha, beta-unsaturated carbonyl compounds.
To solve this problem, we need to predict which cyclic alkene, upon ozonolysis, will produce the appropriate dicarbonyl compound for the aldol condensation reaction to yield the target molecule "x".
The target molecule provided is:
The target molecule "x" looks like it is formed through an aldol condensation reaction. Let's examine the options provided to find the suitable cyclic alkene.
Ozonolysis of cyclic alkenes typically involves breaking the double bonds and forming carbonyl groups at the positions where the double bond was originally present.
The cyclic structure in the target compound suggests it originated from a smaller ring compound with the addition of a carbonyl group.
By examining the options, we are looking for a cyclic alkene that aligns with this reaction pathway.
The correct answer is:
Explanation:
This particular cyclic alkene, upon ozonolysis, will produce a dicarbonyl compound that matches the requirement for the aldol condensation.
Essentially, the ozonolysis cleaves the double bond and oxidizes to form two carbonyl groups, which then can undergo an aldol condensation to form the product.
The structure aligns well with the target molecule after the steps of ozonolysis and subsequent aldol reaction.
To summarize, the predicted suitable alkene is shown, which upon ozonolysis and aldol condensation, will yield the required product “x”.

Approach Solution -2
Given: The desired molecule is obtained via an aldol condensation reaction, starting with an ozonolysis reaction.
Step 1: Ozonolysis
In ozonolysis, an alkene undergoes cleavage to form two carbonyl compounds. These carbonyl compounds can then undergo aldol condensation to form the desired product.
Step 2: Identifying the Correct Alkene
- **Cyclohexene** is the correct choice. - Ozonolysis of cyclohexene will produce **acetone** and **acetaldehyde**, which can then undergo aldol condensation.
Conclusion:
The correct alkene is \( \boxed{\text{Cyclohexene}} \).
