1. Hydrocarbons Integrated Science

2. Rule # 1 Only hydrogen and only carbon

3. Rule # 2 Carbon makes 4 bonds

4. Rule # 3 Hydrogen makes 1 bond

5. Rule # 4 Carbon is the backbone

6. 3 pictures…1 compound

8. Naming Hydrocarbons Use prefixeswith “ane” – 1 carbonmeth-methane – 2 carbons eth-ethane – 3 carbonsprop-propane – 4 carbonsbut-butane – 5 carbonspent - pentane

9. Practice Naming Count the Carbons!

10. Why do we care about hydrocarbons? They are used in combustion reactions…and we all know that we love fire! – Heating Homes – Cooking – Gasoline – Jet fuel – Diesel fuel – Wax – Asphalt

11. Natural Gas has methane

12. Butane is in lighters

13. Gasoline and diesel are full of hydrocarbons Before purified, crude oil has hydrocarbons with 3- 20+ carbons Purified Gasoline < 10 carbons Purified Diesel > 10 carbons Separated by distillation (boiling)…smaller hydrocarbons boil at lower temperatures

14. Asphalt is made from Crude Oil

15. Wax is a mixture of hydrocarbons with 20-40 carbons.

16. Plastics are made from really long hydrocarbons (50+ carbons)
