From this post onwards, we shall study some examples and learn how bonds are formed between two different atoms. Hydrogen fluoride (HF) – We
With this post we start discussing MOT theory for diatomic heteronuclear molecules – molecules formed by two different atoms. The MO diagrams for heteronuclear atoms
Fluorine molecule (F2) – F (9) 1s2 2s2 2p5 Two fluorine atoms bring 7 electrons each to the table and thus the 10 electrons get arranged
Nitrogen molecule (N3) – N (7) 1s2 2s2 2p3 When we construct the MO diagram for nitrogen , we will only draw the valence 2s and
Helium molecule (He2) – He (2) – 1s2. Helium has two electrons in the 1s orbital. Thus, when we draw the MO diagram, two electrons
Pi Symmetry Orbitals with pi symmetry are NOT symmetric w.r.t to the internuclear axis. When rotated around the axis, they produce a phase change (which
Overlaps & Symmetry Based on how the bonds are formed, the interaction between two AOs can have following symmetry- i) Sigma (σ) ii) Pi (π
SYMMETRY OF MOLECULAR ORBITALS. Based on symmetry ,the orbitals can be classified as – GERADE MOs and UNGERADE MOs. Gerade MOs ⇒ Gerade = Even
In this post we shall begin by constructing MO diagrams. We shall begin with the simplest of all homonuclear diatomic molecules – The H2 molecule.
We have seen in the periodic table series , that the electronic configuration tells us where exactly the electron is. Configuration means order… so
LINEAR COMBINATION OF ATOMIC ORBITALS (LCAO approximation) MOT is incorporated in quantum mechanics. As we have already discussed that classical physics (physics
Molecular orbital theory (MOT). This theory assumes that the electrons ,shared between the atoms, are spread throughout the molecule i.e they are NOT
Molecular orbital theory(MOT) is a quantum mechanical approach to bonding.Thus, this theory considers an orbital as a wave function(ψ).In order to understand MOT , it
