Common bond energies

WebThe average bond energy is therefore +1662/4 kJ, which is +415.5 kJ per mole of bonds. That means that many bond enthalpies are actually quoted as mean (or average) bond enthalpies, although it might not actually say so. Mean bond enthalpies are sometimes referred to as "bond enthalpy terms". WebAverage bond energies for some common bonds appear in Table 38.1, and a comparison of bond lengths and bond strengths for some common bonds appears in Table 38.2. When one atom bonds to various atoms in a group, the bond strength typically decreases as we move down the group. For example, C–F is 439 kJ/mol, C–Cl is 330 kJ/mol, and …

WebThe strength of common bonds in living organisms range from 300 to 500 kJ/mol. For example, single carbon–carbon bonds in organic molecules have energies of about 348 kJ/mol (that is, the energy required to break a single carbon–carbon bond is 348 kJ/ mol). Calculate the maximum wavelength of light needed to break the C−C bond. WebThe energy required to break a specific covalent bond in one mole of gaseous molecules is called the bond energy or the bond dissociation energy. The bond energy for a diatomic molecule, D X–Y, is defined as the standard enthalpy change for the endothermic reaction: XY(g) X(g) + Y(g) DX−Y = ΔH ° XY ( g) X ( g) + Y ( g) D X−Y = Δ H ...
