      The reaction of ground-state atomic oxygen [O(${}^3P_2$)] with methyl, ethyl, 𝑛-propyl and isopropyl radicals has been studied using the density functional method and the complete basis set model. The energies of the reactants, products, reaction intermediates and various transition states as well as the reaction enthalpies have been computed. The possible product channels and the reaction pathways are identified in each case. In the case of methyl radical the minimum energy reaction pathway leads to the products CO + H2 + H. In the case of ethyl radical the most facile pathway leads to the products, methanal + CH3 radical. For propyl radical (𝑛- and iso-), the minimum energy reaction pathway would lead to the channel containing ethanal + methyl radical.
