Understanding Crude Oil and Distillation

What is the primary purpose of fractional distillation in the context of crude oil?

• To chemically alter the hydrocarbons

• To separate the components based on boiling points

• To increase the density of crude oil

• To convert crude oil into natural gas

Which of the following is a component of crude oil?

• Ethanol

• Methane

• Petrol

• Water

During fractional distillation, which fraction is collected at the top of the distillation column?

• Bitumen

• Diesel

• Petrol

• Kerosene

What is the main factor that allows hydrocarbons to be separated during fractional distillation?

• Their colour

• Their boiling points

• Their density

• Their viscosity

Which of the following fractions has the highest boiling point?

• Petrol

• Diesel

• Kerosene

• Bitumen

What is the environmental impact of burning fossil fuels like those derived from crude oil?

• Increased oxygen levels

• Decreased carbon dioxide levels

• Air pollution and greenhouse gas emissions

• Improved air quality

Which of the following is NOT a product obtained from the fractional distillation of crude oil?
