Monomers and polymers

• A condensation reaction is when 2 molecules join together via the formation of a new chemical bond, with a molecule of water being released in the process.
• A hydrolysis reaction is when the addition of water breaks the chemical bond, releasing the constituent monomers.
• Monomer: a small repeating unit from which polymers are made
• Polymer: a large, complex molecule composed of a long chain of monomers joined together
