Click hereto get an answer to your question ️ Using molecular orbital theory, compare the bond energy and magnetic character of O2^+ and O2^- species. From this diagram, calculate the bond order for O 2. A) O2^2-B) Ne2^2+ C) O2^2+ D) F2^2+ E) None of the above are paramagnetic; 3) Draw the molecular orbital diagram needed, and determine which of the following is … Molecular orbital diagram for o2 2. In order to draw oxygens molecular orbital diagram you need to start by taking a look at what atomic orbitals you have for an oxygen atom o. A molecular orbital diagram or mo diagram. b) determine the bond order for all three molecules. "O"_2 is well-known to be paramagnetic, and it is one of the successes of molecular orbital theory. Fill from the bottom up with 12 electrons total. Here is the solution, > * For O2 molecule, > * For F2 molecule, Thanks for reading. Reply. Molecular orbital diagram for n2 o2 c2 f2 also h2o. The number of unpaired electrons in O2+ and O22- is, respectively, 1 and 0. O2 molecular orbital diagram oxygen has a similar setup to h 2 but now we consider 2s and 2p orbitals. H–F nb σ σ* Energy H –13.6 eV 1s F –18.6 eV –40.2 eV 2s 2p So H–F has one σ bond and three lone electron pairs on fluorine. The same method can be applied to other diatomic molecules, but involving more than the 1s atomic orbitals.

The Molecular Orbital Theory (often abbreviated to MOT) is a theory on chemical bonding developed at the beginning of the twentieth century by F. Hund and R. S. Mulliken to describe the structure and properties of different molecules. This scheme of bonding and antibonding orbitals is usually depicted by a molecular orbital diagram such as the one shown here for the dihydrogen ion H 2 +. Diagram for O2+ is wrong because 2p atomic orbital of 2nd O atom will have only 3 e-. Bond order is 3 and it is paramagnetic.
