From this post onwards, we shall study some examples and learn how bonds are formed between two different atoms. Hydrogen fluoride (HF) – We begin
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 only draw the valence 2s and 2p orbitals.
Helium molecule (He2) – He (2) – 1s2. Helium has two electrons in the 1s orbital. Thus, when we draw the MO diagram, two electrons occupy
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
Overlap & Symmetry Bonds have different symmetries, based on how they are formed. Bonds in molecules can have the following symmetry – i) Sigma (σ)ii)
SYMMETRY OF MOLECULAR ORBITALS. The orbitals can be classified, based on symmetry as – Gerade and Ungerade MOs. GERADE MOs and UNGERADE MOs. Gerade MOs
In this post, we shall begin by constructing MO diagrams for various molecules. We begin with the simplest of all homonuclear diatomic molecules – The
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
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
