Aim: How are organic compounds named? QQ: What is an isomer? Do Now: Why is it beneficial to have a standardized naming system? Hydrocarbons Compounds consisting only of carbon and hydrogen. Separated by fractional distillation (cracking) based on boiling point. Alkanes Saturated hydrocarbons with all single bonds between carbon atoms CH 4 , C 2 H 6 , C 3 H 8 …C n H 2n+2 methane, ethane, propane… Will always end in “-ane.” Alkenes Unsaturated hydrocarbons with one carbon-carbon double bond present C 2 H 4 , C 3 H 6 , C 4 H 8 …C n H 2n ethene, propene, butene… Will always end in “-ene.” Alkynes Unsaturated hydrocarbons with one carbon-carbon triple bond present C 2 H 2 , C 3 H 4 , C 4 H 6 …C n H 2n-2 ethyne, propyne, butyne Will always end in “-yne.” Naming Hydrocarbons 1.
