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
79. Covalent Bonding(25) – Problems(2).
Q: Which of the following statements for bond angles (θ) in CH4 and CH2F2 molecules is true –A] θ CH4 > θ CH2F2 B] θ CH4 < θ CH2F2 C] θ CH4 = θ
78. CHEMICAL BONDING (25)- Covalent Bonding(24) – Problems(1).
Q: Why does PCL5 exist but NCl5 does not?A. Ionization energy of N is very highB. N does not have vacant d- orbitalsC. It does
77. Covalent Bonding(23) – Drago Rule (2).
THE DRAGO RULE. Drago rule states that if – the central atom has at least one lone pair of electron on it. the central atom
76. Covalent Bonding(22) – Drago Rule (1).
This post is all about asking the right questions to arrive at the desired answer. We will study certain observations that do not follow the
75.Covalent Bonding(21)- Hybridization in solid-state.
How do compounds exist in solid-state? Compounds exist as ions in the solid-state. Consider the following example – PCl5 molecule – This molecule has trigonal
