Hydrocarbon Classification
Aliphatics: open chains
1. alkanes ("paraffins"): contain only carbon-carbon single bonds (are saturated). General formula: Chttp://scienceworld.wolfram.com/chemistry/himg42.gifHhttp://scienceworld.wolfram.com/chemistry/himg43.gif.
2. alkenes ("olefins"): contain a single carbon-carbon double bond. General formula: Chttp://scienceworld.wolfram.com/chemistry/himg42.gifHhttp://scienceworld.wolfram.com/chemistry/himg44.gif.
3. alkynes: contain a single carbon-carbon triple bond. General formula: Chttp://scienceworld.wolfram.com/chemistry/himg42.gifHhttp://scienceworld.wolfram.com/chemistry/himg45.gif.
Cycloaliphatics: closed chains
1. cycloalkanes: general formula: Chttp://scienceworld.wolfram.com/chemistry/himg42.gifHhttp://scienceworld.wolfram.com/chemistry/himg44.gif.
Aromatics: contain benzene rings and their
.derivatives.
