Study Notes
Organic compounds are used to create polymers, which are large molecules formed from smaller units called monomers. Different polymers have unique monomer units and linkages, leading to diverse properties and uses. Plastics, a type of synthetic polymer, pose environmental challenges due to their non-biodegradable nature and difficulty in disposal.
Exam Tips
Key Definitions to Remember
- Polymer — Large molecules made from repeating units called monomers.
- Monomer — Small molecules that join together to form polymers.
- Addition Polymerization — A process where monomers with double bonds form polymers without losing any atoms.
- Condensation Polymerization — A process where monomers join to form polymers with the loss of small molecules like water.
Common Confusions
- Confusing addition polymerization with condensation polymerization.
- Misunderstanding the environmental impact of synthetic polymers.
Typical Exam Questions
- What is a polymer? A large molecule made from repeating monomer units.
- How does addition polymerization differ from condensation polymerization? Addition polymerization involves no loss of atoms, while condensation polymerization involves the loss of small molecules.
- Why are plastics considered an environmental challenge? They are non-biodegradable and difficult to dispose of.
What Examiners Usually Test
- Ability to define and differentiate between types of polymerization.
- Understanding of the environmental implications of synthetic polymers.
