O2的键级是2,O2(+)是拿掉反键轨道上的一个电子,因此键级增大0.5。
第二章分子结构2-1画出O2、H2O2、CO、CO2、NCl3、SF4的路易斯结构式。不要忘记标出孤对电子和分子的总电子数。解:O2:共12eH2O2:共14eCO:共10e︰C≡O︰CO2:共16eNCl3:共26eSF4:共34e2-2画出硫酸根各共振体的结构式。解:BondOrder:theaveragenumberofbondsconnectinganelementtothecentralatomBondOrder(B.O....
This commentary focuses on the conceptual interpretation of the bonding of O 2 and NO to heme in oxyheme and nitrosylheme complexes, using high-level ab initio complete active space self-consistent field (CASSCF)/molecular mechanical (MM), gas-phase CASSCF, and CASSCF followed by second-order ...

Explain why the boiling points of the components of a mixture should differ by at least 40 degrees Celsius in order to get an effective separation by simple distillation. H2 + Br2 = 2HBr Suggest two reasons why all the collisions between hydrogen and bromine gas molecules do not result in ...
The determination of the bond energy is usually performed indirectly by measuring the heat of adsorption (or heat of desorption) of the gas [1, 2], In order to define the heat of adsorption, let us consider the chemisorption of a diatomic molecule, X2, onto a site on a uniform solid ...
The nature of the interoxygen bonding in O2, HO2, H2O2, O3, HO3, and H2O3has been investigated on the basis ofab initio(LCAO‐MO) and experimental force constants, bond lengths, and energies. The fact that small basis sets appear to give the OO force constants for H2O2and HO2in the...
g) What is the overall bond order of O2? ---> For this, do I just use BO=(#e-in bonding - #e-in antibonding)/2 to give me 2. h) How many electrons must be added to O2 to reduce the bond order to zero? --->For this one, would it be four because then it would be BO...
Synthesis of NO2, and C–N–O organics direct from N2 and O2, rather than from an intermediate NH3 (known as the Haber–Bosch process), is tantalizing. However, the extremely strong N≡N triple bond (945 kJ mol–1) and the nonpolar stable electron configuration of dinitrogen lead to ...
