Petroleum is divided into fractions by fractional distillation. The separation takes place in a fractionating column. Some properties of three of these fractions are given below. Fraction 1: the molecules contain $5\text{-}10$ carbon atoms. Fraction 2: boiling point range $320\text{-}350\,^\circ\text{C}$, the molecules contain $16\text{-}24$ carbon atoms. Fraction 3: boiling point range $120\text{-}210\,^\circ\text{C}$. Which statement 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.
