l
What is the raw
material for making
plastics?
Crude oil
Give a definition of a polymer.
Very large long chain molecule made up
of lots of small repeating units called
monomers
Why is it important to recycle
plastics?
They are made from crude oil, which
is a finite resource.
We are running out of landfill space
Give
a
definition
of
a
hydrocarbon Compound made of
hydrogen and carbon atoms only
Describe how you would test a
hydrocarbon to find out if it was
unsaturated. Include the expected
result in your answer.
Shake with bromine water
Turns orange to colourless if
unsaturated.
What is the function of a
catalyst?
To speed up a chemical
reaction.
What is cracking?
Breaking long chain hydrocarbons
into smaller, more useful molecules.
What groups of molecules are produced
by cracking?
Alkanes and alkenes
What is an alkene.
Unsaturted
hydrocarbon.
What is the general formula for an
alkene? CnH2n
Draw the structure of propene and give
its molecular formula.
What is a biodegradable polymer?
Polymer that can be decomposed by soil
microbes
What substance is
used to make a plastic
biodegradable?
Cornstarch
Why are hydrogels
useful?
They absorb water
C3H6
What is the name of the process when ethanol is
made from sugar?
fermentaiton
Complete the diagram below to show the formation
of PVC from chloroethene
What catalyst is used to
crack hydrocarbons in
the lab?
Ceramic pot
What
special
property
does
a
shape
memory
polymer have?
Returns

shape
following heating or
cooling
Give an advantage and a disadvantage of
making ethanol from sugar cane.
There is a plentiful supply of sugar cane /
sugar cane is renewable (unlike crude oil)
Uses crops that would otherwise be used
for food / takes a lot of space
Name this molecule
ethene
Draw a diagram to show
the product of reaction
between
ethene
and
bromine water?
Write an equation for the
formation of ethanol from ethene.
Ethene + water -> Ethanol
