A hydrocarbon weighing 112 g with the formula C_H_ is burned in air to produce 3285 g of. The formula for acyclic saturated hydrocarbons ie alkanes is C n H 2n 2. All alkanes are composed of carbon and hydrogen atoms and have similar bonds structures and formulas.
They may contain branches which are considered substitutes for the hydrogens on a straight chain.
