Why is there a large difference in the boiling points of butanal and butan-1-ol?

Answer :

There is a large difference in the boiling points of butanal and butan-1-ol, i.e. aldehyde and alcohol of the same molecular mass. This is due to the presence of intermolecular hydrogen bonding in butan-1-ol, whereas there is no intermolecular hydrogen bonding in butanal. This bonding makes butan-1-ol slightly more stable at a higher temperature than butanal.
