9.2.1 Ethylene & polymers
What is the systematic name of the following structure?
What is the product X called which is obtained from the steam cracking of ethane?
X + H
Ethylene (ethene) contains a highly reactive double bond that supplies electrons to other reactants.
Ethylene can be readily transformed into many useful products.
Which of the following products is correctly matched with it use?
ethanoic acid (steriliser)
ethylene oxide (plastic)
polyethylene (food preservative)
During the production of polyethylene two activated chains of varying length collide to produce a stable polymer chain. This step occurs at during the
Catalytic cracking is used in the petrochemical industry to break down large hydrocarbons into smaller molecules. The following reaction is an example
What is the name of product Z?
Polystyrene is a hard rigid plastic that can be readily remoulded. The strength of this polymer is due to
extensive cross linking between the polystyrene chains
bulky side groups that prevent the chains slipping over one another
a linear packaging arrangement of polymer chains
a highly branched polymer chain structure
What type of reaction involves the opening the opening of a double bond in the monomer in order to join onto neighbouring monomers?
An addition reaction
A condensation reaction
An oxidation/ reduction reaction
A dehydration reactiion

The following monomer is used to make what series of products?
CD cases, petri dishes and screw driver handles
raincoats, waste water pipes and insulation for electrical wires
milk bottles, grocery carry bags and aerosol lids
cling wrap products, soft squeeze bottles and ice cream container lids
