Cracking

The video explains the process of cracking, which uses heat to break down long hydrocarbon chains into smaller, more useful hydrocarbons like alkenes. These alkenes are essential in manufacturing plastics. Additionally, the process can convert heavy hydrocarbons such as bitumen into lighter, more combustible fuels like petrol and propane.

What is the primary purpose of cracking in hydrocarbon processing?

• To combine small hydrocarbons into larger ones

• To split long hydrocarbon chains into smaller, more useful ones

• To cool down hydrocarbons for storage

• To remove impurities from hydrocarbons

Which type of hydrocarbons are produced through the cracking process?

• Cycloalkanes

• Alkenes

• Alkanes

• Aromatics

What is one of the end products of cracking that is used to manufacture plastics?

• Alkenes

• Butane

• Methane

• Propane

What type of hydrocarbons can be transformed into lighter fuels through cracking?

• Heavy hydrocarbons like bitumen

• Light hydrocarbons

• Solid hydrocarbons

• Gaseous hydrocarbons

Which of the following is a lighter, more combustible fuel produced from cracking?

• Kerosene

• Diesel

• Petrol

• Lubricating oil
