1. The Chemistry of Carbon Do Now: Please Copy (Ignore what is on handout): Quiz Thursday 10/6 Topics: Special Properties of Water Polarity & Hydrogen Bonding in Water Solutions pH and buffers

2. Carbon What is it? Where do we find it? Why is it so important? How is it unique?

3. Carbon: Element of Life Plants and other autotrophs build their own carbon- based food out of CO2 in the air. Animals and other heterotrophs break down carbon-based food for energy

4. Carbon is Important! Natural Gas, Gasoline, Crude Oil, and other fuels are all carbon compounds All plastics The molecules organisms are made of, like sugars, fats, proteins, and even DNA. Too many to list!!!

5. Carbon forms many types of bonds Carbon has 4 valence electrons, so it usually makes 4 covalent bonds. Most atoms make less (O-2, H-1, N- 3) Organic Compound: a compound that contains 2 or more carbon atoms.

6. Carbon can form different structures… Chains Branched Chains Rings

7. …and form single, double, & even triple bonds.

8. Functional Groups give carbon molecules even more diversity. A functional group is a group of atoms that give the molecule they are a part of certain chemical characteristics.

9. Carbon Polymers – Essential to Life! MONOMER POLYMER

10. In Summary… Organic compounds contain more than 1 carbon atom Carbon is REQUIRED by ALL living things – other than water, it is in almost every other chemical your body is made of. Because carbon can make 4 covalent bonds, and bond with many other elements, carbon can make many different types of chemicals. Many organic compounds are polymers: long chains of repeating subunits

11. Read all about it! (Homework) Read pp. 52-54 NOT last section “Energy Currency” Answer 1-3

12. Life in Deep Space? The article you have discusses recent discoveries of carbon compounds in space. Read the article on your own 4 roles to play in each group: Questioner, Passage Master, Word Wizard, or Artful Artist

13. Polymer Formation and Break-down
