In a fractionating tower,the crude oil vapors pass from a pipe still into the column.Tar and lubricating stock are the first components to be pulled off at the bottom.Nearer the top kerosene is pulled off followed by gasoline and finally natural gas at the very top.From this information,which has a higher boiling point,gasoline or kerosine?


A) Gasoline has the higher boiling point.
B) Kerosene has the higher boiling point.
C) Their boiling points are the same,but kerosene has the greater density.
D) Fractional distillation components are pulled off based on molecular weight,so it is not possible to know which has the higher boiling point from the information given.
