The 'energy levels' tool is useful in lectures as it shows the relationship between the molecular orbital diagram and the bond character of a polar covalent bond and combines a graphical and a numerical approach. The 'MO diagram maker' is useful as for students for practice and as a self-test of their understanding. You can write a book review and share your experiences. Other readers will always be interested in your opinion of the books you've read. Whether you've loved the book or not, if you give your honest and detailed thoughts then people will find new books that are right for them.

- 77. O=N‒Cl: The bond order of the NO bond in NOCl is 2 (a double bond). NO: From molecular orbital theory, the bond order of this NO bond is 2.5. Both reactions apparently involve only the breaking of the N‒Cl bond. However, in the reaction ONCl → NO + Cl, some energy is released in forming the stronger NO bond, lowering the value of ΔH.
Molecular Orbital Theory was postulated by R.S. Mulliken and F. Hund. It explains the state of bonded electrons in a molecular orbital, which can be represented as a linear combination of atomic orbitals (LCAO). Molecular orbitals are polycentric, where electrons are influenced by more than one nucleus.In H2+when two hydrogen atoms come closer, then on combining two 1s orbitals,two molecular orbitals are formed among which one is bonding and other is antibonding molecular orbital. Now on adding one electron to H2, H2- is formed. What is the order of the bond length among H2, H2+, and H2-?

So from the molecular orbital diagram there are two unpaired electrons thus the molecule is paramagnetic in nature. Similarly we can also construct molecular orbital diagram for Florine molecule. Florine atom contains 9 electrons so electronic configuration is 1s2, 2s2 and 2p5.Molecular Structure For an s orbital, the orbital has the same phase everywhere: For a p orbital, there is a change in the sign of the wavefunction across the nodal plane: 2p orbital, n = 2, l = 1, ml = -1 1s orbital, n = 1, l = 0 Molecular Structure Consider two H atoms (1s1) coming together from infinite separation.
