Polyme
rsCarbon-based compounds
1.Build a molecule of ethane, ethene and ethyne.
2.Build a molecule of butane and then build an isomer of butane (isobutane).
Polyme
rsCarbon-based compounds
1. INFER:1. How does JELLO (a carbon-
based compound) become a solid?
2. How does your body produce hair, muscle and skin?
3. How can they make a solid plastic out of liquid petroleum,
or rubber out of liquid sap?
MOLECULES OF LIFE
We are all CBLF’s (carbon-based life forms)
•CARBON CAN FORM AN INCREDIBLE VARIETY OF MOLECULES!!!
BASIC STRUCTURAL FEATURES:A. MULTIPLE BONDS
•SINGLE BONDS: -ane •DOUBLE BONDS: - ene•TRIPLE BONDS: -yne
POLYMERSPOLYMERS• Carbon atoms can bond to one
another in chains to form a variety of structures, including fossil fuels such as coal, synthetic polymers such as plastics, and the large molecules of life, such as proteins and lipids.
Molecular structure of Coal
Lipid
Polyethylene
All of this allows Carbon to create: GIANT MOLECULES called POLYMERS100’s to 1000’s of smaller molecules
joined together.Polymers ARE CHAINS OF Monomers
joined together.

Carbon Polymers - Journal
1. Define “polymer”. Define “monomer”.2. Name the 3 main types of polymers and give
an example of each 3. Draw the structural formula for the monomer
“ethylene” and part of the structural formula for the polymer “polyethylene”
4. Define polymerization5. What is a “Catalyst”? (use your
resources)
Polymers
• Polymerization: When carbon molecules combine into long chains.
• HOW: This happens when a carbon to carbon double bond in a monomer is broken and new single bonds are formed creating a polymer.

Polymers
Living organisms form biopolymers such as carbohydrates, proteins, lipids and nucleic acids through polymerization.
FOUR TYPES OF ORGANIC POLYMERS:
1.CARBOHYDRATES – glucose, bread, pasta
CARBO(C) – HYDRATE(H2O)2.PROTEINS – muscle, meat, hair,
nails3.LIPIDS – fat, oil, butter4.NUCLEIC ACIDS – DNA, RNA
>ALL CONTAIN C, H, AND O>C—C BONDS ORGANIC COMPOUNDS

Polymers
NOT ALL REACTIONS CAN GO BY THEMSELVES.
Catalyst: A chemical substance that STARTS or INCREASES the rate of a reaction without being used in the polymer.

Polymers
Catalyst: A chemical substance that increases the rate of a reaction without being consumed.
Carbon Polymers - Review
1. Carbon atoms bonded to one another in chains
2. 3 TYPES: fossil fuels, synthetic polymers, and biopolymers
3. Formed through a process called polymerization
4. Catalyst: STARTS or INCREASES the rate of the reaction without being used up
Carbon Polymers - Journal
1. Write down the name, and some of the properties of the plastic on your desk.
2. Quick draw an image of both the monomer and polymer of ethylene.
3. Re-Read the Polymer Lab Sheet from the back of the room.
4. Choose which test (tensile, abrasion, puncture) that you would want to run, and begin filling out the back of the
sheet.
