Organic Carbon Compounds What is a hydrocarbon? What are their properties? • Hydrocarbons are compounds containing only hydrogen (H) and carbon (C)
Organic Carbon Compounds Some hydrocarbon formulas… Some structural formulas of hydrocarbons • CH4 C2H6 C3H8 C4H10
Organic Carbon Compounds Structural formulas are important because the same combination of carbon and hydrogen atoms can bond in different ways. • CH4 C2H6 C3H8 C4H10 C4H10

Polymers Polymers can be fun – like SLIME! We’ll look at how it works, then we will make some. vinyl acetate monomer Vinyl acetate is a monomer that makes a polymer found in some glues.
Polymers Polyvinyl acetate is the polymer found in glue.
Polymers Borax is sodium borate, Na3BO3. The borax actually dissolves to form boric acid, H3BO3. This boric acid-borate solution is a buffer with a pH of about 9 (basic). Boric acid will accept a hydroxide OH- from water
Polymers Borate ions from cross links between the long polymer molecules. This causes the long polymers to get all stuck together .
