Table of bond energies
WebBond energies in kJ/mol C-H single bond = 412 kJ/mol, O=O double bond = 496 kJ/mol, C=O double bond = 803kJ/mol, H-O single bond = 463 kJ/mol Solution Step 1: Energy required to break the bonds = 4* (C-H) + 2* (1* O=O) = (4*412) + (2*496) = 1648 + 992 = 2640kJ/mol Step 2: Energy released while forming bonds = (2*C=O) + 2* (2*O-H) WebThe bond energies of several specific bonds are shown in this table. Bond energies between certain pairs of atoms vary somewhat, depending on the particular molecule they are part of, because adjacent atoms can affect their bonding slightly. The values in Table II are average bond energies for the listed bonds.
