Question

The number of aldol reaction(s) that occurs in the given transformation is: \[ \text{CH}_3\text{CHO} + 4\text{CH}_3\text{CHO} \]

• A. 1
• B. 2
• C. 3
• D. 4

Hint:

In aldol reactions, the number of reactions depends on the number of molecules involved in the condensation.

Answer 1

The Correct Option is C

Step 1: Understand the aldol condensation.
Aldol reaction is the condensation between two carbonyl compounds. The reaction given shows the condensation of 5 molecules of acetaldehyde.
Step 2: Conclusion.
Thus, the number of aldol reactions is 3.
Final Answer: \[ \boxed{3} \]
