1. Carbon Chemistry Chapter 8

2. Organic Compounds Organic compounds are compounds composed of carbon based molecules. examples: sugar, starch, fuels, synthetic materials like plastic

3. Organic Compounds The backbone of organic compounds is carbon because it has 4 valence electrons and each atom can form 4 separate bonds The backbone of organic compounds is carbon because it has 4 valence electrons and each atom can form 4 separate bonds

4. Organic Compounds Carbon compounds can form in 3 different Arrangements 1) Straight Chain 2) Branched chain 3) ring

6. Organic Compounds 1) Chemical formulas showing kind and number of atoms using symbols and subscripts 1) Chemical formulas showing kind and number of atoms using symbols and subscripts 2) Structural formulas showing kind, number and arrangement of atoms 2) Structural formulas showing kind, number and arrangement of atoms

7. Example: Acetone Chemical Formula: C 3 H 6 O Chemical Formula: C 3 H 6 O Structural formula: Structural formula:

8. Organic Compounds Carbon compounds with the same chemical formula but different structural formulas are called isomers

9. Organic Compounds Isomers 1) are different forms of the same compound with different properties and characteristics 2) There can be so many different isomers of carbon because carbon can form single, double and triple bonds.

10. Examples of Isomers Butane: C 4 H 10

11. Types of Bonds

12. Organic Compounds Polymers are very large molecules made up of many smaller molecules bonded together. The smaller molecules are called monomers Polymers can be made by living things (natural) or in factories (synthetic)

13. Organic Compounds Organic compounds are formed mostly from the elements carbon, and hydrogen but can also include elements like oxygen, nitrogen, phosphorus, sulfur, and others but can also include elements like oxygen, nitrogen, phosphorus, sulfur, and others H. Hydrocarbons are organic compounds formed from only hydrogen and carbon

14. II. Life with Carbon A)Simple carbohydrates are substances like glucose B) Complex carbohydrates are substances like starches and cellulose Organic compounds made by living things are very large molecules. They are: 1) Carbohydrates: made of different types of simple sugars blended together; used for energy

15. Simple and Complex Carbohydrates

16. Life with Carbon 2) Proteins are polymers made of amino acids. used to build and repair body parts and regulate cell activity 3) Lipids: (fats) are made of fatty acids and do not dissolve in water used to store energy

17. 4) Nucleic Acids are very large polymers made of nucleotides. There are 2 types: DNA and RNA 4) Nucleic Acids are very large polymers made of nucleotides. There are 2 types: DNA and RNA used to store information and help build proteins used to store information and help build proteins

18. 5) Smaller molecules required by living things Vitamins - used to help in a variety of chemical reactions Water- used to dissolve nutrients and carry them throughout the body Minerals - used to form ions needed by the body (not organic) Salt- used to help muscles contract and transmission of nerve impulses
