Addition Polymerisation

What is a monomer?

• A small molecule that joins with others to form a polymer

• A large molecule composed of repeating units

• A molecule made only from single bonds

What is a polymer?

• A single unit of a compound

• A molecule made from a single element

• A long molecule made from repeating units of monomers

Which type of reaction links alkenes into polymers?

• Substitution

• Addition

• Condensation

Which type of bond opens up during addition polymerisation?

• C–H bond

• C=O bond

• C=C double bond

Which hydrocarbon is used to make poly(ethene)?

• Ethene

• Ethane

• Propane

What is the smallest unsaturated hydrocarbon?

• Ethene

• Methane

• Propene

Why is ethene suitable for making polymers?

• It contains only single bonds

• It contains a double bond that can open up and link molecules

• It is the largest alkane

What is poly(propene) made from?

• Propanol

• Propene

• Butene

What does the polymerisation of alkenes form?

• A chain of saturated hydrocarbons

• A chain of unsaturated hydrocarbons

• A chain of alcohols

What is true of the repeating unit in a polymer?

• It includes the original double bond

• It is fully saturated

• It is a different monomer than the original
