What is a monomer?

A monomer is a smaller unit that combines to make a polymer.

What is a polymer?

A polymer is a large molecule made up of many repeating units of monomers joined together by chemical bonds.

What is the process by which monomers join to form a polymer?

Monomers join via polymerisation.

What type of reaction synthesises most polymers?

Polymers are synthesised via a condensation reaction.

What type of reaction breaks down most polymers?

Polymers are broken down via a hydrolysis reaction.

What is a condensation reaction?

A reaction where monomers join together and release a water molecule.

What is a hydrolysis reaction?

A reaction where a water molecule is added to break a chemical bond between two molecules
