Quick explanation
In addition polymerisation reactions, many small molecules (monomers) join together to form very large molecules (polymers)
- This point belongs to Reactions of alkenes and alcohols (chemistry only), especially Polymerisation and naturally occurring polymers.
- You need to be able to in addition polymerisation reactions, many small molecules (monomers) join together to form very large molecules (polymers).
- The key ideas to know are monomer, addition polymerisation, and polymer.
- Use the linked flashcards and practice questions to check recall, then practise applying the idea in an exam-style answer.
Key concepts
Why it matters
This objective helps connect Polymerisation and naturally occurring polymers to exam-style questions, flashcards, and revision notes for Reactions of alkenes and alcohols (chemistry only).
Quick student answer
What should you know about addition polymerisation reactions, many small molecules (monomers) join together to form very large molecules (polymers)?
Direct answer
In Chemistry, this page helps you answer questions about addition polymerisation reactions, many small molecules (monomers) join together to form very large molecules (polymers) within Reactions of alkenes and alcohols (chemistry only). Focus on the key process, correct scientific terms, and how the idea links to exam-style questions. Key terms to check are monomer and polymer.
Key terms
- monomer: A small molecule that can join together with other monomers to form a polymer.
- polymer: A large molecule made up of repeating units of monomers, formed through polymerisation.
Common trap
Misunderstanding Monomers and Polymers: Remember that monomers are the small molecules that join together to form large molecules called polymers. Focus on the definition and examples of each.
