Petroleum is divided into fractions by fractional distillation. The separation takes place in a fractionating column. The properties of three of these fractions are listed below. A table shows: - fraction 1: the molecules contain 5-10 carbon atoms - fraction 2: boiling point range $320$-$350\,^{\circ}\text{C}$, the molecules contain 16-24 carbon atoms - fraction 3: boiling point range $120$-$210\,^{\circ}\text{C}$ Which statement below is correct?
- AFraction 1 has a higher boiling point range than fraction 2.
- BFraction 2 is removed from a higher point in the fractionating column than fraction 1.
- CMolecules in fraction 3 have shorter chains than those in fraction 2.
- DNone of the fractions are liquid at room temperature.
