Why does bitumen have a higher boiling point than kerosene?

The hydrocarbon chains are shorter in bitumen

There are fewer intermolecular forces between bitumen molecules

Bitumen is found at the bottom of the fractionating column

The hydrocarbon chains are longer in bitumen and as such there are greater intermolecular forces
