CO in high concentration is fatal in less than 5 mins !! The worst part is that this is an odorless and colorless gas and

92. Covalent Bonding(38) – MOT(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 begin
91.Covalent Bonding(37) – MOT(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
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
