S2.Induced dipole– Induced dipole interactions. Vander Waals bond, London dispersion force and induced dipole-induced dipole interactions all mean the same. This type of interaction is operative
97. Secondary bonding(1)- Dipole-dipole interactions.
We have already seen in post # 54, that the main difference between primary and secondary bonding is that in secondary bonding, there is NO
96. Metallic bonding (2).
As discussed in the previous post, the free electron gas model was not infallible. Almost 30 years after the electron gas model was proposed, quantum
95. Metallic bonding(1).
P3.THE METALLIC BOND. In this post, we shall discuss the last kind of primary bond – The metallic bond. We see many objects in our everyday
94.Co-ordinate Covalent Bond.
This post is dedicated to studying the co-ordinate covalent. This is a bond formed between an electron-rich and an electron-poor species. Electron rich species →
93.Covalent Bonding(39) – MOT(12)- Heteronuclear diatomic molecules(3).
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.
In the previous post we understood that hetero nuclear molecules are formed by two different atoms with similar energies. From this post onwards, we shall
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
