What are alkanes and cycloalkanes ?

Alkanes. Alkanes are the saturated hydrocarbons. They contain only carbon-carbon and carbon-hydrogen single bonds. They are represented by the general formula.CnH2n+2 (where n = 1, 2, 3, 4.......etc.). For example,
n = 1 CH4 Methane
n = 2 C2H6 Ethane
n = 3 C3H8 Propane
n = 4 C4H10
 Butane
n = 5 C5H12 Pentane
n = 6 C6H14 Hexane
n = 7 C7H16 Heptane
n = 8 C8H18 Octane
n = 9 C9H20 Nonane
n = 0 C10H22 Decane

Cycloalkanes: Saturated alicyclic hydrocarbons in which all the carbon atoms are joined by single covalent bonds are called cycloalkanes. These are represented by the formula CnH2n if they are monocyclic and CnH2n_2 in case they are bicyclic. For example,
