Organic Compounds
• relating to, or derived from living matter
• compounds containing carbon.

Remember valence e-
• C atoms share 4 e- to achieve an octet (8).
• C can bond in many ways

Carbon ChainsIsomer: Two or more compounds with the same formula but different bonds and different properties.
![Page 10: 1. Ammonium chloride NH 4 Cl 2. Aluminum oxide Al 2 O 3 3. Ferric oxide Fe 2 O 3 4. Potassium carbonate 3K 2 (CO) 3 Do Now – count the atoms for each element](https://reader036.vdocuments.site/reader036/viewer/2022070412/56649ec95503460f94bd71e2/html5/thumbnails/10.jpg)
Carbon ChainsSmall molecules are called monomers and when joined together they form polymers.
![Page 11: 1. Ammonium chloride NH 4 Cl 2. Aluminum oxide Al 2 O 3 3. Ferric oxide Fe 2 O 3 4. Potassium carbonate 3K 2 (CO) 3 Do Now – count the atoms for each element](https://reader036.vdocuments.site/reader036/viewer/2022070412/56649ec95503460f94bd71e2/html5/thumbnails/11.jpg)
Small Molecules Support the function of larger molecules.
