Question

Why do fluorocarbons have lower boiling point than hydrocarbons

Answer 1

Answer:

The increased boiling point is easily explained by the stronger dipole-dipole attraction.

The graph shows that the polar effect diminishes as the size of the molecule increases. ...

However, above 4 carbon atoms the boiling points of the perfluorocarbons are less than the hydrocarbons indicating weaker attractive forces.
