An unified formula for deriving the molecular composition of hydrocarbons

An unified method of designing molecular formulae for all types hydrocarbons is proposed in this paper. The developed formula provides the molecular composition of hydrocarbons regardless of the number of chemical bonds and bond types or the number of rings they contain. Moreover, a small modification to that formula makes it suitable for deriving the molecular composition of hydrocarbons with oxygen atoms bound to carbon atoms with single and double bonds.
