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.
