MCQ
The alcohol which does not give a stable compound on dehydration is
  • A
    Ethyl alcohol
  • Methyl alcohol
  • C
    $n-$propyl alcohol
  • D
    $n-$butyl alcohol

Answer

Correct option: B.
Methyl alcohol
b
Alcohols undergo dehydration (removal of water) to form an alkene.

To form alkene, we need at least two carbon atoms. But, methanol $\left( CH _3 OH \right)$ has only one carbon atom. So, it does not give a stable compound on dehydration.
