Answer:
ethyne
Explanation:
Bond dissociation energy or homolytic dissociation energy is defined as the energy required to break the covalent bond present in a compound homolytically.
Homolysis is the breakage of a single bond. therefore, this energy represents the energy needed to break the bonds singly
ethene has a bond dissociation energy of 730KJ/mol while ethyne has a bond dissociation energy of 964KJ/mol. the energy needed to break the bonds of ethyne is higher than that needed to break the bonds of ethene
