- Alkanes formula - Cn H 2n+2
- Alkanes are a family of hydrocarbons.
- They only contain single covalent bonds.
- The alkane family contains molecules that look similar, but have different length chains of carbon atoms.
- Methane - CH4 Ethane - C2H6, Propane - C3H8 and Butane - C4H10.
- Alkanes burn to give carbon dioxide and water as long as there is plenty of oxygen around.
- Alkanes don't react with most chemicals - unreactive.
- They don't react with aqueous reagents because the C-C bonds and C-H bonds in them are unreactive.
