Hemistry is the technology approximately breaking and forming of bonds among atoms. the most very important approaches for natural chemistry is breaking bonds C–H, in addition to C–C in quite a few compounds, and basically, in hydrocarbons. between hydrocarbons, saturated hydrocarbons, alkanes (methane, ethane, propane, hexane and so on. ), are particularly beautiful as substrates for chemical changes. the reason is,, at the one hand, alkanes are the most parts of oil and usual gasoline, and hence are the central feedstocks for chemical undefined. nonetheless, those elements are recognized to be the fewer reactive natural compounds. Saturated hydrocarbons should be referred to as the “noble gases of natural chemistry” and, if this is the case, the 1st consultant in their kin – methane – should be in comparison with tremendous inert helium. As in all comparisons, this parallel among noble gases and alkanes isn't totally exact. certainly the alterations of alkanes, together with methane, were identified for a very long time. those reactions contain the interplay with molecular oxygen from air (burning – the most resource of energy!), in addition to a few mutual interconversions of saturated and unsaturated hydrocarbons. even though, these kinds of adjustments take place at increased temperatures (higher than 300–500 °C) and tend to be characterised via an absence of selectivity. The conversion of alkanes into carbon dioxide and water in the course of burning is an incredibly precious strategy – yet now not from a chemist standpoint.
