  2. Molecular orbital diagram - Wikipedia

    en.wikipedia.org/wiki/Molecular_orbital_diagram

    Molecular orbital diagram of dinitrogen. With nitrogen, we see the two molecular orbitals mixing and the energy repulsion. This is the reasoning for the rearrangement from a more familiar diagram. The σ from the 2p is more non-bonding due to mixing, and same with the 2s σ. This also causes a large jump in energy in the 2p σ* orbital.

  3. Nitric oxide - Wikipedia

    en.wikipedia.org/wiki/Nitric_oxide

    Nitric oxide (nitrogen oxide or nitrogen monoxide [1]) is a colorless gas with the formula NO.It is one of the principal oxides of nitrogen.Nitric oxide is a free radical: it has an unpaired electron, which is sometimes denoted by a dot in its chemical formula (• N=O or • NO).

  4. Nitrogen - Wikipedia

    en.wikipedia.org/wiki/Nitrogen

    Molecular orbital diagram of dinitrogen molecule, N 2. There are five bonding orbitals and two antibonding orbitals (marked with an asterisk; orbitals involving the inner 1s electrons not shown), giving a total bond order of three. Atomic nitrogen, also known as active nitrogen, is highly reactive, being a triradical with three unpaired electrons.

  5. Pi backbonding - Wikipedia

    en.wikipedia.org/wiki/Pi_backbonding

    σ bonding from electrons in alkene's HOMO to metal center d-orbital. π backbonding from electrons in metal center d-orbital to alkene's LUMO. As in metal–carbonyls, electrons are partially transferred from a d-orbital of the metal to antibonding molecular orbitals of the alkenes and alkynes.

    Nitrogen oxide may refer to a binary compound of oxygen and nitrogen, ... Nitric oxide (NO), nitrogen(II) oxide, or nitrogen monoxide; Nitrogen dioxide (NO 2 ...

  7. Molecular orbital - Wikipedia

    en.wikipedia.org/wiki/Molecular_orbital

    Molecular orbitals are said to be degenerate if they have the same energy. For example, in the homonuclear diatomic molecules of the first ten elements, the molecular orbitals derived from the p x and the p y atomic orbitals result in two degenerate bonding orbitals (of low energy) and two degenerate antibonding orbitals (of high energy). [13]

  8. Triple bond - Wikipedia

    en.wikipedia.org/wiki/Triple_bond

    The p-orbitals are perpendicular to the sp-orbitals on the y-axis and the z-axis. When the atoms approach each other, the sp orbitals overlap to form an sp-sp sigma bond. At the same time the p z-orbitals approach and together they form a p z-p z pi-bond. Likewise, the other pair of p y-orbitals form a p y-p y pi-bond. The result is formation ...

  9. Bond order - Wikipedia

    en.wikipedia.org/wiki/Bond_order

    Here the sum extends over π molecular orbitals only, and n i is the number of electrons occupying orbital i with coefficients c ri and c si on atoms r and s respectively. Assuming a bond order contribution of 1 from the sigma component this gives a total bond order (σ + π) of 5/3 = 1.67 for benzene, rather than the commonly cited bond order ...
