Alkanes
What are Alkanes?
The simplest of organic molecules, comprising of only carbon and hydrogen and with only single
bonds between carbon atoms.
More information about Alkanes
Also known as a Paraffin, an Alkane does not dissolve in water, but does dissolve in an organic solvent. For example: Oil not dissolving in water
Some basic Alkanes include: Ethane
Propane
MethaneButane
Products containing Alkane Plastics: Paints:
Drugs: Cosmetics:
Detergent: Insecticides:
Facts about Methane
• Odorless• Invisible• Combustible • Methane is the simplest alkane • Ranks second as a green house gas
next to carbon dioxide (CO2)
Facts about Propane• Exists as a liquid and a gas • Used in 48 million households and
businesses. • 270x more compactable as a liquid
than gas • Kept at an atmospheric pressure and
temperature above -44℉ is:1. Odorless2. Invisible3. Non-Toxic4. Combustible
Facts about Ethane
• Odorless• Colorless• Can be soluble in polar substances
(like water) • Highly Combustible • Widely used for quickening the
process of food ripening • Used as a refrigerant in refrigeration
systems along with butane
Facts about Butane
• Usually found in a bottled form sold for camping stoves, out-door powered grills and cigarette lighters.
• Added to gasoline to boost performance • When compressed it becomes a liquid;
however, when it is released into the air and reacts with an ignition source it becomes an extremely flammable gas.
• Only releases CO2 as a waste product as apposed to CO.
List of
Alkanes
Additional Facts
• Alkanes have the general chemical formula CnH2n+2.
• Chemically; alkanes are relatively unreactive.
• They are obtained by fractional distillation from petroleum and are used extensively as fuels.
