Homolytic bond dissociation energy of C-H bond is minimum for

Bond dissociation energy of CH_(4) si 360 kJ/mol and C_(2)H_(6) has 620 kJ mol. Then bond dissociation energy of C-C bond is :-

Bond dissociation energy of CH_(4) is 360 kJ/mol and C_(2)H_(6) is 620 kJ/mol. Then bond dissociation energy of C-C bond is-
