Which of the following on reaction with Grignard's reagent followed by hydrolysis forms tertiary alcohol?
Show Hint
Ketone + Grignard = $3^\circ$ Alcohol.
Updated On: Apr 30, 2026
- Methanal
- Ethanal
- Propanal
- Propanone
Show Solution
Verified By Collegedunia
The Correct Option is D
Solution and Explanation
Step 1: Concept
Grignard reagents ($RMgX$) react with carbonyl compounds to form alcohols after hydrolysis.
Step 2: Analysis
- Formaldehyde (Methanal) $\rightarrow$ Primary ($1^\circ$) alcohol. - Other Aldehydes (Ethanal, Propanal) $\rightarrow$ Secondary ($2^\circ$) alcohol. - Ketones (Propanone) $\rightarrow$ Tertiary ($3^\circ$) alcohol.
Step 3: Conclusion
Propanone (Acetone), being a ketone, will yield a tertiary alcohol.
Final Answer: (D)
