Which feature of a monomer allows it to undergo addition polymerisation?
Answer and explanation
Correct answer: D. A carbon-to-carbon double bond
- Step 1: Addition polymerisation opens the C=C double bond.
- Step 2: The monomers then join together to form a long chain.
Answer
A carbon-to-carbon double bond.
Why not the others: A hydroxyl group: this is in alcohols. A carboxyl group: this is in carboxylic acids. A ring of carbon atoms: cycloalkanes do not add.
