Updated On: Oct 6, 2026
- $2CH_3CHO \xrightarrow{dil. NaOH, \Delta}$
- $2CH_3COCH_3 \xrightarrow{Ba(OH)_2, \Delta}$
- $CH_3CHO + HCHO \xrightarrow{dil. NaOH, \Delta}$
- $C_6H_5COCH_3 + C_6H_5CHO \xrightarrow{dil. NaOH, \Delta}$
Show Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
Step 1: Concept
Aldol condensation: Mesityl oxide is formed from acetone.
Step 2: Meaning
Acetone undergoes self-aldol condensation followed by dehydration to yield mesityl oxide.
Step 3: Analysis
$2(CH_3)_2CO \rightarrow (CH_3)_2C=CHCOCH_3$ (Mesityl oxide).
Step 4: Conclusion
Option B is the correct reaction.
Final Answer: (B)
