Question

why is there is a large difference in the boiling point of butanal and butan-1-ol

Answer 1

yes there is a large difference between in the boiling point of butanal and butan-1-ol because butanal and butanol have different structures different properties.Butanal aldehyde is there and in batan-1-ol alcohol is there

Answer 2

Answer: Because of the presence of hydrogen bonding in butan-1-ol

Explanation:

Boiling point is the temperature at which vapor pressure of the liquid becomes equal to atmospheric pressure.

The boiling point of a liquid depends on the extent of inter molecular forces present in the compound. The more are the forces , more heat is required to generate enough vapors and thus higher is the boiling point.

Butanal molecules are bonded by weak dipole dipole interactions whereas butan-1-ol molecules are bonded by strong hydrogen bonds which are difficult to break and thus have higher boiling point.
