Alkanes

=__Alkanes__= Alkanes are saturated hydrocarbons which contain only single carbon-carbon bonds. It is saturated because there is a hydrogen in every possible location. This gives them a general formula of CnH2n+2.

Examples of alkane :


 * **Carbon** || **Name** || **Molecular**

 * 1 || Methane || CH4 || CH4 ||
 * 2 || Ethane || C2H6 || CH3CH3 ||
 * 3 || Propane || C3H8 || CH3CH2CH3 ||
 * 4 || Butane || C4H10 || CH3CH2CH2CH3 ||
 * 5 || Pentane || C5H12 || CH3CH2CH2CH2CH3 ||
 * 6 || Hexane || C6H14 || CH3(CH2)4CH3 ||
 * 7 || Heptane || C7H16 || CH3(CH2)5CH3 ||
 * 8 || Octane || C8H18 || CH3(CH2)6CH3 ||
 * 9 || Nonane || C9H20 || CH3(CH2)7CH3 ||
 * 10 || Decane || C10H22 || CH3(CH2)8CH3 ||

1) Find the longest chain of carbons and it does not have to be straight. This goes at the end of the name. Eg) If it contains 3 carbons, it will be propane.

2) Identify any side branches and these go just before the longest chain name, along with the number of the carbon it comes off.

3) If you get more than one side chain, indicate how many times it occurs. This goes just before the branch name. Eg) //di//- two , //tri//-three , //tetra-//four
