3. Alkenes Unsaturated Hydrocarbons At least one double bond in the carbon chain More reactive than alkanes Formula –C n H 2n –To figure out number of Hydrogen's Names end in –ene –Ex. Ethene

4. Alkene Examples Butene 3,4 dimethyl 2pentene –Why is it numbered that way? 1,5 octadiene 4 butyl cyclohexene

5. Alkynes Unsaturated Hydrocarbons At least one triple bond in the carbon chain More reactive than alkanes and alkenes Formula –C n H 2n - 2 –To figure out number of Hydrogen's Names end in –yne –Ex. Ethyne

6. Alkyne Examples Butyne 4-heptyne 4ethyl, 2 methyl, 1 hexyne
