Alkanes and Alkenes

• Hyrdocarbons are organic compounds that contain carbon and hydrogen. There are 4 general classes of hyrdocarbons; Alkanes, Alkenes, Alkynes and Arenes.

  What is Hydrocarbons?
• Alkanes is a single bond of carbon and hydrogen bonded along the sides.


  What is Alkanes?
• Alkanes general formula is CnH2n+2, and n = number of carbons


  General Formula for Alkanes
• methane, ethane, propane, butane, pentane, hexane, heptane, octane, nonane, decane

  What is the first 10 Alkanes
• Alkanes is also called saturated hyrdocarbons, meaning the atoms have single bonds


  What is Alkanes called?
• Alkenes are unsaturated hydrocarbons with at least one carbon-to-carbon double bond. Because Alkenes must have one double carbon bond, it means that there is no 1 carbon alkene.


  What is Alkenes?
• Alkenes have the general formula; CnH2n, and n = number of carbons.


  General formula for alkenes
• When bromine water(orange) comes into contact with alkanes, it stays orange. If bromine water comes into contact with alkene, it turns colourless.
