Why bond strength in this order? Given ΔH°= -311 kJ for the hydrogenation of acetylene, C2H2: H-C≡C-H(g) + 2 H2(g) → CH3-CH3(g), Very short distance the energy rises steeply because of the great importance of the internuclear repulsive forces at these distances, thebond length is the distance at which the system has minimum energy, and the bond energy corresponds to the depth of the "well" at this distance. Bond dissociation energies Yu-ran Luo The bond dissociation energy (enthalpy) is also referred to as bond disruption energy, bond energy, bond strength, or binding energy (abbreviation: BDE, BE, or D) .
