MCQ
Which of the following alcohol does not give a stable compound on dehydration?
- AEthyl alcohol
- ✓Methyl alcohol
- C$n-$propyl alcohol
- D$n-$butyl alcohol
✓
Answer
Correct option: B.
Methyl alcohol
Alcohols undergo dehydration $($removal of water$)$ to form an alkene.
To form alkene, we need at least two carbon atoms. But, methanol $(\mathrm{CH}_3 \mathrm{OH})$ has only one carbon atom. So, it does not give a stable compound on dehydration.
