Study Notes

Hydrocarbons

The general formula for alkanes is CnH2n+2, where n is the number of carbon atoms.

Aromatic Hydrocarbons

Aromatic hydrocarbons do not have a property of being saturated.

IUPAC Nomenclature

The IUPAC name for a hydrocarbon with 6 carbon atoms and a double bond is hex-2-ene.

Close Chain Hydrocarbons

A close chain hydrocarbon is a type of hydrocarbon that has a continuous chain of carbon atoms.
Example: hexane (C6H14) is a close chain hydrocarbon.
Unique properties of close chain hydrocarbons include:
- They have a higher boiling point compared to branched chain hydrocarbons.
- They have a higher melting point compared to branched chain hydrocarbons.
