Assessment Evidence:

Your research will help journalists and the general public understand the importance of organic chemistry

This will come from completing the tasks but you may wish to include any extra information that you find.

How you present your work is up to you, but you should discuss this with your teacher.

Remember to list any websites or books you have used in a bibliography

Scenario: We all know that oil is being used faster than it is being produced. As a journalist you have been asked to research a newspaper article to get people to appreciate the number of products that are obtained from oil. You should consider the advantages and disadvantages of using the products of oil.Produce details of what we might have to do without in the future if oil runs out. You need to include information about how we use these products and the quantities used by an average citizen – you can make estimates based on your own use.

Your Work Should Include…..

1) What is an organic compound?

2) Combustion reactions

Write up a practical where you have burned an organic compound.

Who burns fuels?

Why do they burn them? (PASS).

3) The petrochemicals industry

How do we separate crude oil?

Why is this necessary?

What do we use the “fractions” for? (PASS).

4) Polymers

How do we convert alkanes into alkenes?

How can we test alkenes and alkanes to tell the difference?

How can we turn alkenes into polymers?

What are polyethene and PVC?

What are they used for? (PASS),

5) Oxygen containing organic compounds

What are the differences between alcohols and carboxylic acids?

How can we test alcohols and carboxylic acids to tell the difference?

What are the uses of alcohols and carboxylic acids? (PASS).

What are the problems with alcohol and carboxylic acids?

6) Advantages and Disadvantages

●What are the environmental affects of burning fuels? (use the carbon cycle)

● Why do we use fuels? What are the alternatives

● Explain the advantages and disadvantages of fractional distillation and cracking

● What are the environmental problems with using plastics

● What are the advantages of using plastics?

● What are the problems with alcohol and carboxylic acids? (MERIT)

7) Structures and names

Investigate the structures and names of the following groups of organic compounds: alkanes, alkenes, chloroalkanes, chloroalkenes, alcohols, and carboxylic acids

For each group you should:

a) Give a dot/cross diagram to show the bonding in one example, name it, and give its molecular formula.

b) Make a 3 dimensional model, and draw it in “atom and stick” style.

c) For the alkanes only, give names and structures from C1 through to C8.

d) Give a “general formula” for each group of compounds.
