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.

1. As a ‘starter’ for this week please attempt the Microsoft Form on the

work you completed last week on Isomers and Cracking. The link for it is

here: https://forms.office.com/Pages/ResponsePage.aspx?id=oyzTzM4Wj0KVQTctawUZKe

Please note that you need your glow username and password to access the

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.

3. Self Check – 16.

4. Homework – 11.

1.

2.

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.

3.

4.

Again, you DO NOT need to

learn what the different

fractions are or what they’re

used for.

5.

6.

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.
