1 Unit 2: Chemical Interactions Chapter 8: Carbon Chemistry Big Idea: Because of its ability to combine in many ways with itself & with other elements, carbon has a central role in the chemistry of living organisms

2 Mrs. Lee - Ch 82 4 Sections 1.Properties of Carbon 2.Carbon Compounds 3.Polymers & Composites 4.Life with Carbon

3 Mrs. Lee - Ch 83 Sec 1: Properties of Carbon KEY CONCEPTS Because of its ability to combine in many ways with itself & other elements, carbon has a central role in the chemistry of organisms The 4 forms of the element carbon are: 1) diamond 2) graphite 3) fullerenes 4) nanotubes

4 Mrs. Lee - Ch 84 Sec 1: Key Terms Diamond Graphite Fullerene Nanotube

5 Mrs. Lee - Ch 85 Sec 2: Carbon Compounds KEY CONCEPTS Many organic compounds have similar properties in terms of melting points, boiling points, odor, electrical conductivity, & solubility Hydrocarbons mix poorly with water. Also, all hydrocarbons are flammable

6 Mrs. Lee - Ch 86 Sec 2: Carbon Compounds (cont’d) The carbon chains in a hydrocarbon ring may be straight, branched, or ring-shaped. In addition to forming a single bond, two carbon atoms can form a double bond or a triple bond If just one atom of another element is substituted for a hydrogen atom in a hydrocarbon, a different compound is created

7 Mrs. Lee - Ch 87 Sec 2: Carbon Compounds (cont’d) Many esters have pleasant, fruity smells Organic compounds can be linked together to build polymers with thousands or even millions of atoms

8 Mrs. Lee - Ch 88 Sec 2: Key Terms Organic compound Hydrocarbon Structural formula Isomer Saturated hydrocarbon Unsaturated hydrocarbon Substituted hydrocarbon Hydroxyl group Alcohol Organic acid Carboxyl group Ester Polymer Monomer

9 Mrs. Lee - Ch 89 Sec 3: Polymers & Composites KEY CONCEPTS Polymers form when chemical bonds link large numbers of monomers in a repeating pattern Many composite materials include one or more polymers You can help reduce the amount of plastic waste by recycling

10 Mrs. Lee - Ch 810 Sec 3: Key Terms Protein Amino acid Plastic Composite

11 Mrs. Lee - Ch 811 Sec 4: Life with Carbon KEY CONCEPTS The 4 classes of organic compounds required by living things are: 1) carbohydrates 2) proteins 3) lipids 4) nucleic acids The energy released by breaking down starch allows the body to carry out its life functions

12 Mrs. Lee - Ch 812 Sec 4: Life with Carbon (cont’d) The body uses proteins from food to build & repair body parts & to regulate cell activities Gram for gram, lipids release twice as much energy in your body as do carbohydrates When living things reproduce, they pass DNA & the information it carries to the next generation Organisms require water, vitamins, minerals, & salts to help support the functioning of large molecules

13 Mrs. Lee - Ch 813 Sec 4: Key Terms Carbohydrate Glucose Complex carbohydrate Starch Cellulose Lipid Fatty acid Cholesterol Nucleic acid DNA RNA Nucleotide
