A Level Chemistry Revision “Separation of Alkanes by Fractional Distillation”

You can find all my A Level Chemistry videos fully indexed at https://www.freesciencelessons.co.uk/a-level-revision-videos/a-level-chemistry/

In this video, we look at how the alkanes in crude oil are separated by fractional distillation. First we explore how the boiling point of an alkane depends on the length of the carbon chain. Next we look at the stages of fractional distillation.

This video is aimed at the UK A Level Chemistry specifications. Students studying International A Level Chemistry will need to check their specification.
