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
74.Covalent Bonding(20)- Bent’s rule(3).
Example 3 – PCl3F2 molecule . This molecule has TBP geometry, with two F atoms and three Cl atoms as substituents. According to Bent’s rule,
73.Covalent Bonding(19)- Bent’s rule(2).
After having learned the statement of Bent’s rule in the earlier post, let us now study the rule with some examples. We know that bond angle(θ) ∝ %
72.Covalent Bonding(18)- Bent’s rule(1).
In this post, we are going to learn a comparatively new rule, proposed by Henry Bent. Henry Bent (1926-2015) was an American physical chemist who
71. Covalent Bonding(17)- The Bond Angle.
We have already studied that the angle between the central and terminal atoms of a molecule is called a bond angle. In this post, we
70. Covalent Bonding(16)- Isovalent hybridization.
In the last post, we have seen that the bond angles (θ), hybridization index (i), and the fraction of s and p character in a
