GCSE Chemistry - Cracking Crude Oil & Alkenes #54

The video tutorial explains crude oil as a mixture of hydrocarbons and how they can be separated by fractional distillation. It introduces the process of cracking, which breaks down long hydrocarbons into shorter, more useful ones using thermal decomposition. Two methods, catalytic and steam cracking, are discussed. The video also covers writing balanced chemical equations for cracking reactions, using decane as an example. Finally, it highlights the properties of alkenes, their reactivity, and their ability to form polymers.

How do you determine the number of carbons and hydrogens in the products of a cracking reaction?

What is the structural difference between alkenes and alkanes?

What happens to bromine water when it is added to a solution of alkenes?
