Saturated compounds (alkanes)maximum number of hydrogen
atoms attached to each carbon atom
Unsaturated compounds fewer hydrogen atoms attached to
the carbon chain than alkanesUnsaturated compounds contain double or triple bonds
Saturated and Unsaturated Compounds
Carbon-carbon double bondsNames end in -eneH2C=CH2 ethene (ethylene)H2C=CH-CH3 propene (propylene)
cyclohexene
Alkenes
Carbon-carbon triple bondsNames end in -yneHC CH ethyne(acetylene)
HC C-CH3 propyne
Alkynes
When the carbon chain has 4 or more C atoms, number the chain to give the lowest number to the double or triple bond.

Naming Alkenes and Alkynes
Write the IUPAC name for each of the following unsaturated compounds:
CH3CH2C CCH3
CH3CH3C=CHCH3
Learning Check HA3
2-pentyne
2-methyl-2-butene
3-methylcyclopentene
Double bond is fixedCis/trans Isomers are possible
Cis and Trans Isomers
Adds a hydrogen atom to each carbon atom of a double bond
