The dissociation of ethane involves the breaking of the C-C bond. Under this process, the high molecular symmetry of ethane leads to the production of two identical fragments. Each of these moieties retains an unpaired electron, representing Lewis' concept of shared electron pairs. In some instances, this dissociation may also result in two charged fragments. Remarkably, the dissociation of ethane is not a simple process. It demands a significant amount of energy. Experimental data estimates this to be around 89.9 kcal/mol at 298 K in the gas phase. In our studies using the complete active-space self-consistent field (CASSCF) and its second-order perturbation theory (CASSPT2) methods, we found a range of required energies deviating from 1.56 to 8.15 kcal/mol.
