Arrange the following in decreasing order of their boiling points: n-Butanol, 2-Methylpropan-1-ol, 2 β Alcohols Phenols and Ethers Chemistry Question
Question
Arrange the following in decreasing order of their boiling points: n-Butanol, 2-Methylpropan-1-ol, 2-Methylpropan-2-ol.
Answer: A
π‘ Solution & Explanation
Among isomeric alcohols, the boiling point decreases with an increase in branching because the surface area decreases, leading to weaker van der Waals dispersion forces. Thus, straight-chain n-butanol has the highest boiling point.
