Topic(s) –Fractional Distillation
This set of work is to be done over the week from Wednesday 27th
May to Friday 29th May (Monday is a May holiday for you all,
Tuesday is an in-service).
Here is a list of the resources you should be using this week, on the
following pages the resources have been screenshotted so you all
only need this one document open to work from for the whole
week.
Video solutions to homework 9 and 12 can be found in the files
section now.

form.
2. Notes to copy into notes jotter and learn – Fractional Distillation.
Instructions/teaching points are in the text boxes, in bold and italic text.
There are 6 notes in total. If you have the option to do so at home, feel
free to print and stick them into your notes jotter, especially the
diagrams – you would never need to draw these in an exam.

You need to be aware of where the Hydrocarbons you have been learning about over the last few weeks
come from, but you DO NOT NEED TO LEARN of by heart the Fractional Distillation process.
YOU DO NEED TO LEARN how normal distillation works, but you will learn plenty more about this in the
next topic on alcohols.
This is the process distilleries
use to produce whisky, gin
and vodka.
Petrol is given an ‘octane
number’ this is how much of
the petrol is made up of
Octane. The more octane
there is, the more expensive
the petrol is. The more
octane in petrol the better
the engine runs.
E.g. ‘Super-Unleaded’ has an
octane number of 98 but
‘standard unleaded petrol’
has an octane of 95 and is
much cheaper.
