Fractional Distillation

What is crude oil?

• Processed oil

• Synthetic oil

• Unprocessed oil

• Refined oil

What happens to small molecules with weaker intermolecular forces?

• They require less energy to turn into gas

• They have higher boiling points

• They require more energy to break apart

• They condense at the bottom of the column

Where are long-chain molecules with high boiling points collected in the fractional distillation column?

• In the middle of the column

• At the top of the column

• At the bottom of the column

• They remain in vapor form

Which fraction is used as aircraft fuel?

• Petrol

• Kerosene

• Diesel oil

• Naphtha

What is the main purpose of fractional distillation?

• To increase the boiling points of hydrocarbons

• To mix hydrocarbons

• To separate crude oil into useful fractions

• To create synthetic oil
