Methane CH4 does not have a carbon-carbon single bond. It consists of one carbon atom bonded to four hydrogen atoms. Therefore, it is not possible to calculate the bond dissociation energy required to break a carbon-carbon single bond in methane. However, if you would like to know the bond dissociation energy for breaking a carbon-hydrogen bond in methane, I can provide that information.The bond dissociation energy for a carbon-hydrogen bond in methane is approximately 439 kJ/mol.
