92.CHEMICAL BONDING (39)- Covalent Bonding(38) – Molecular Orbital Theory(13)- Heteronuclear diatomic molecules(2)- HF.
From this post onwards, we shall study some examples and learn how bonds are formed between two different atoms. Hydrogen fluoride (HF) – We
91.CHEMICAL BONDING (38)- Covalent Bonding(37) – Molecular Orbital Theory(12) – Heteronuclear Diatomic molecules(1)
With this post we start discussing MOT theory for diatomic heteronuclear molecules – molecules formed by two different atoms. The MO diagrams for heteronuclear atoms

Nitrogen molecule (N3) – N (7) 1s2 2s2 2p3 When we construct the MO diagram for nitrogen , we will only draw the valence 2s and
88.CHEMICAL BONDING (35)- Covalent Bonding(34) – Molecular Orbital Theory(9)- Helium ,sp mixing.
Helium molecule (He2) – He (2) – 1s2. Helium has two electrons in the 1s orbital. Thus, when we draw the MO diagram, two electrons
87. CHEMICAL BONDING (34)- Covalent Bonding(33) – Molecular Orbital Theory(8) – Overlaps and symmetry(2)
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
86.CHEMICAL BONDING (33)- Covalent Bonding(32) – Molecular Orbital Theory(7) – Overlaps and symmetry(1)
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
84. CHEMICAL BONDING (31)- Covalent Bonding(30) – Molecular Orbital Theory(5).
In this post we shall begin by constructing MO diagrams. We shall begin with the simplest of all homonuclear diatomic molecules – The H2 molecule.
83.CHEMICAL BONDING (30)- Covalent Bonding(29) – Molecular Orbital Theory(4)- LCAO approximation(2).
We have seen in the periodic table series , that the electronic configuration tells us where exactly the electron is. Configuration means order… so
82.CHEMICAL BONDING (29)- Covalent Bonding(28) – Molecular Orbital Theory(3)- LCAO approximation(1).
LINEAR COMBINATION OF ATOMIC ORBITALS (LCAO approximation) MOT is incorporated in quantum mechanics. As we have already discussed that classical physics (physics
81.CHEMICAL BONDING (28)- Covalent Bonding(27) – Molecular Orbital Theory(2).
Molecular orbital theory (MOT). This theory assumes that the electrons ,shared between the atoms, are spread throughout the molecule i.e they are NOT
80.CHEMICAL BONDING (27)- Covalent Bonding(26) – Molecular Orbital Theory(1).
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
