Certain interstellar reactions have been studied through the graphtheoretic method using a Fortran-77 program. A plausible mechanism has been proposed for the reactions. The criterion of the conversion of edge to loop and vice versa proposed by the Bratislava group [Theor. Chim. Acta 79, 65 (1991)] has been given a reasonable chemical insight. In the reaction scheme the nucleophilic/electrophilic/carbene (singlet, triplet) or biradical loops have been generated by the fragmentation of reactant. Subsequently, Pearson's hard and soft acids bases (HSAB) theory and frontier orbital (FO) theory have been applied to explain the reaction mechanism. Few possible reactions of the interstellar and circumstellar molecules have been investigated with illustrations involving carbene intermediate and Woodward-Hoffmann rule.
