Question 84

Crude oil is a finite resource consisting predominantly of alkanes, which can be separated into useful fractions by fractional distillation. Which of the following mixtures contains only formulas of compounds that would typically be found in the liquid petrol (gasoline) fraction, containing hydrocarbons with 5 to 12 carbon atoms, obtained directly from the fractional distillation of crude oil?
