    Can someone explain the process of fractional distillation in some key simple points so I can just remember key points instead of sentences on end?

    Like if it was a six mark question in a GCSE chemistry paper: Explain the process of fractional distillation.

    I have my exam in a week ._.

    Fractional distillation (the key points you need to know).

    - Crude oil contains a mixture of different hydrocarbon molecules. This mixture is not very useful.
    - Through the process of fractional distillation, more useful fractions are formed.
    - Each fraction is a simpler mixture than crude oil.
    - Examples of useful products formed: Gasoline, petrol and heating oil.

    These are the key points/ideas.

    Also just add that the reason why they separate is because they are heated and each of the compounds within the mixture have different boiling points due to a difference in intermolecular forces allowing them to be separated ..
