WebbHence, dissociation of a primary carbon-hydrogen bond will be difficult, requiring the most energy. In case of tertiary carbon, this energy required will be least. Therefore, order of … WebbBond energy is inversely proportional to the bond length. Down the group the size of molecules increases and thus the bond length increases. But chlorine molecule has greater bond energy than the fluorine molecule. Because fluorine is too small, so repulsive forces are more dominating in the fluorine molecule as compared to the chlorine molecule.
