Presentation on theme: "Carbon-based compounds"— Presentation transcript:
1 Carbon-based compounds Build a molecule of ethane, ethene and ethyne.Build a molecule of butane and then build an isomer of butane (isobutane).PolymersCarbon-based compounds
2 Polymers Carbon-based compounds INFER: How does JELLO (a carbon-based compound) become a solid?How does your body produce hair, muscle and skin?How can they make a solid plastic out of liquid petroleum, or rubber out of liquid sap?
3 MOLECULES OF LIFE We are all CBLF’s (carbon-based life forms) CARBON CAN FORM AN INCREDIBLE VARIETY OF MOLECULES!!!
6 D. RINGS - Aromatics Each corner represents a carbon atom. Ring size can vary from three to eight.
7 POLYMERS Polyethylene 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.LipidMolecular structure of Coal
8 All of this allows Carbon to create: GIANT MOLECULES called POLYMERS 100’s to 1000’s of smaller molecules joined together.Polymers ARE CHAINS OF Monomers joined together.
9 polymer 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.monomerpolymer
10 POLYMERS (the whole train) are made out of MONOMERS (individual cars of the train) joined together.
12 Carbon Polymers - Journal Define “polymer”. Define “monomer”.Name the 3 main types of polymers and give an example of eachDraw the structural formula for the monomer “ethylene” and part of the structural formula for the polymer “polyethylene”Define polymerizationWhat is a “Catalyst”? (use your resources)
13 PolymersPolymerization: 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.
14 PolymersPolymerization of polypropylene (propene).
19 Polymers: ProteinsPolymerization of a protein: putting simple monomers together.
20 Polymers: ProteinsPolymerization of a protein: putting simple monomers together.Where will the monomers JOIN TOGETHER?monomermonomermonomermonomer
21 Polymers: ProteinsPolymerization of a protein: putting simple monomers together.Where will the monomers JOIN TOGETHER?monomermonomermonomermonomer
22 Polymers: ProteinsPolymerization of a protein: putting simple monomers together.Water drops out to allow the bonds to form.
23 Polymers: ProteinsPolymerization of a protein: putting simple monomers together.
24 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.
25 PolymersCatalyst: A chemical substance that increases the rate of a reaction without being consumed.
26 Carbon Polymers - Review Carbon atoms bonded to one another in chains3 TYPES: fossil fuels, synthetic polymers, and biopolymersFormed through a process called polymerizationCatalyst: STARTS or INCREASES the rate of the reaction without being used up
27 Carbon Polymers - Journal Come inHave a seatSilently read the article from the back
28 Carbon Polymers - Journal Write down the name, and some of the properties of the plastic on your desk.Quick draw an image of both the monomer and polymer of ethylene.Re-Read the Polymer Lab Sheet from the back of the room.Choose which test (tensile, abrasion, puncture) that you would want to run, and begin filling out the back of the sheet.
