With this post, we start discussing MOT theory for diatomic heteronuclear molecules – molecules formed by two different atoms. The MO diagrams for heteronuclear atoms

90. Covalent Bonding(36) – MOT(11) – Fluorine.
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
89. Covalent Bonding(35) – MOT(10)- Nitrogen molecule.
Nitrogen molecule (N3) – N (7) 1s2 2s2 2p3 When we construct the MO diagram for nitrogen, we only draw the valence 2s and 2p orbitals.
88. Covalent Bonding(34) – MOT(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 occupy
87. Covalent Bonding(33) – MOT(8) – Overlaps and symmetry(2)
Pi (π) Symmetry Orbitals with π symmetry are NOT symmetric w.r.t to the internuclear axis. When rotated around the axis, they produce a phase change
86. Covalent Bonding(32) – MOT (7) – Overlaps and symmetry(1)
Overlap & Symmetry Bonds have different symmetries, based on how they are formed. Bonds in molecules can have the following symmetry – i) Sigma (σ)ii)
85. Covalent Bonding(31) – MOT(6)- Symmetry of MOs.
SYMMETRY OF MOLECULAR ORBITALS. The orbitals can be classified, based on symmetry as – Gerade and Ungerade MOs. GERADE MOs and UNGERADE MOs. Gerade MOs
84. Covalent Bonding(30) – MOT(5).
In this post, we shall begin by constructing MO diagrams for various molecules. We begin with the simplest of all homonuclear diatomic molecules – The
83.Covalent Bonding(29) – MOT(4)- LCAO approximation(2).
Configuration means order. The electronic configuration of an element describes how electrons are distributed in various atomic orbitals in the atom. Thus, electronic configuration gives
82.Covalent Bonding(28) – MOT(3)- LCAO approximation(1).
LINEAR COMBINATION OF ATOMIC ORBITALS (LCAO approximation) Classical physics and quantum mechanics are two very different approaches. Classical physics comprises all the theories that were
81. Covalent Bonding(27) – Molecular Orbital Theory(2).
The Molecular Orbital Theory (MOT). This theory assumes that the electrons, shared between the atoms, are spread throughout the molecule. These electrons are NOT localized
80. Covalent Bonding(26) – Molecular Orbital Theory(1).
Molecular orbital theory(MOT) is a quantum mechanical approach to bonding. This theory considers an orbital as a wave function(ψ).In order to understand MOT, it is
