Arrange pentan-1-ol,n-butane,pentanal ,ethoxyethane in order of their increasing boiling points?

Open in App

Solution

Increasing order due to functional groups: Alkane has only London dispersion forces, ethoxyethane is just polar, aldehydes have C=O double bonding leading to more polarity and alcohols have hydrogen bonding.
n-butane < ethoxyethane < pentanal < pentanol
