Because oxygen is more electronegative than carbon, an O-H bond has a larger bond dipole than a C-H bond. Hence the force of attraction between two water molecules is greater than it is between two methane molecules. Water has the higher boiling point. ... Therefore, methane has the higher boiling point.

What has a higher boiling point butane or methane?

The intermolecular forces of attraction in methane, ethane, propane and butane are van der Waals forces. ... Thus, the van der Waals forces are weakest in methane and strongest in butane. Stronger the intermolecular force, higher is the boiling point because more energy will be required to break the bonds.

Which gas has higher boiling point?

Among the noble gases, Xe has the highest boiling point.
