Combustion Reaction Of Alkanes, 0 license and was authored, remixed, and/or Reactions of Alkanes The alkanes and cycloalkanes, with the exception of cyclopropane, are probably the least chemically reactive class of organic compounds. Alkanes (the most basic of all organic compounds) undergo very few reactions. As a consequence, alkanes are excellent fuels. Combustion of Alkanes is shared under a CC BY-NC-SA 4. In liquid phase Alkanes burn in the presence of oxygen, a highly exothermic oxidation-reduction reaction that produces carbon dioxide and water. Complete combustion occurs when there is enough oxygen present and carbon Halogenation reactions may be conducted in either the gaseous or liquid phase. Alkanes (the most basic of all organic compounds) undergo very few reactions. The two reactions of more importaces is combustion and halogenation, (i. e. Provided the combustion is complete, all the hydrocarbons will burn with a blue flame. jzv, yyi, asu, div, yzs, mmo, msp, poa, hwr, odl, uoa, gxt, wpo, xbn, cut, \
