An ether is more volatile than an alcohol having the same molecular formula. This is due to
Detailed Solution for Test: Alcohols, Phenols and Ether & Aldehydes, Ketones and Carboxylic Acids (February 23) - Question 15

The correct answer is Option D.
An ether is more volatile than an alcohol having the same molecular formula. This is due to intermolecular hydrogen bonding in alcohols. In alcohols, H atoms are attached to electronegative O atoms. Due to this, H atom of −OH group of one alcohol molecule forms a hydrogen bond with the O atom of −OH group of the second alcohol molecule. This results in the intermolecular association. It increases the boiling point and decreases the volatility of alcohol. Such intermolecular hydrogen bonding is not possible in others as in ethers, H atoms are not attached to an electronegative O atom.
