NEET Chemistry Chemical Reactions MCQ Question
What is the order of increasing boiling points among the following alcohols: methanol, ethanol, propan-1-ol, butan-1-ol?
Methanol < Ethanol < Propan-1-ol < Butan-1-ol
Butan-1-ol < Propan-1-ol < Ethanol < Methanol
Ethanol < Methanol < Butan-1-ol < Propan-1-ol
Propan-1-ol < Butan-1-ol < Methanol < Ethanol
Correct Answer
Detailed Explanation
The boiling point of alcohols increases with the increase in the length of the carbon chain due to stronger intermolecular forces. Hence, methanol has the lowest and butan-1-ol has the highest boiling point among the given alcohols.
