It decreases the boiling point.

Vedclass · Answer

(B) The boiling point of an alkane depends on the surface area of the molecule. As branching increases,the shape of the molecule approaches that of a sphere,which reduces the surface area. This decrease in surface area leads to weaker van der Waals forces of attraction between the molecules. Consequently,less energy is required to overcome these forces,resulting in a decrease in the boiling point.
