Surface reactions on warm (T/sub g/> or approx. =60 K) graphite grains between lattice C atoms and impinging H and O atoms, within or in the vicinity of H II regions, can provide a prolific source of H/sub 2/CO and other interstellar molecules. It is proposed that similar reactions in the primitive solar nebula led to the formation of the organic molecules found in carbonaceous chondrites. From this and related evidence it is argued that most of the solid material in the solar system may have originated as interstellar grains.
