By-products of Common Reactions
One of the most significant sources of heat energy are the combustion of carbon compounds; especially hydrocarbons. As combustion is a very complex reaction, no other reaction involves such a pervasive change. For example, in the combustion of propane, every covalent bond in the reactants side has been broken and formed a new set of covalent bonds for the products.
CH3-CH2-CH3 + 5 O2 ——> 3 CO2 + 4 H2O + heat
Unlike combustion reactions, halogenation is the replacement of a hydrogen atom in an organic compound by a halogen such as bromine, chlorine, or fluorine. This reaction is containing an alkane is a substitution reaction when a C-H bond breaks and a C-X bond is formed. An example of this type of reaction is the chlorination of methane:
CH4 + Cl2 + energy ——> CH3Cl + HCl
As the C-H and Cl-Cl covalent bonds are broken, C-Cl and H-Cl are formed. (Reusch, 2013) This is a substitution reaction in which a saturated hydrocarbon or benzene reacts with a halogen or hydrogen, resulting in a hydrogen halide and a halocarbon compound. (Mogck, 2014)
