1. 1. Hexane 2. 3-methylheptane 3. 2,4-dimethylehexane 4. 4-ethylheptane 5. 3-ethyl-2, 3-dimethylhexane 6. Butane 7. 3-ethyl-1-pentene 8. 2-methyl-5-propylheptane 9. 2,3,4-trimethylheptane 10. 2-bromo-4-methylhexane

2.  Hydrocarbons  Alkanes (single C-C bond)  Alkenes (double C=C bond)  Alkynes (triple C = C bond)  Alcohols  Ketones  Carboxylic Acids

4. 1. Use longest chain 2. Indicate position of double bond by a prefix number that is the carbon atom attached by the double bond and nearest the end of the chain. - C - C - C = C 3. For more than 1 double bond, change ending  2 double bonds – diene  3 double bonds – triene C = C - C - C - C = C – C - 1-butene 1, 5-heptadiene

5.  Complete #11-23  Try #24 - 40
