MCQ
Which of the following alcohol does not give a stable compound on dehydration?
  • A
    Ethyl alcohol
  • B
    Methyl alcohol
  • C
    n-propyl alcohol
  • D
    n-butyl alcohol
✓

Answer

  1. Methyl alcohol

Explanation:

Alcohols undergo dehydration (removal of water) to form an alkene. 

To form alkene, we need at least two carbon atoms. But, methanol (CH3​OH) has only one carbon atom. So, it does not give a stable compound on dehydration.
