102.CHEMICAL BONDING (49)- Secondary bonding(6)- Hydrogen Bonding (4)
We continue to study the physical manifestations of H- bonds and their importance. Protein folding Hydrogen bonds are an integral part of the protein structure.
101.CHEMICAL BONDING (48)- Secondary bonding(5)- Hydrogen Bonding (3)
We studied hydrogen bonding in the last two posts. In this post, we will study the types of this bonds and their implications . The H-bond
100.CHEMICAL BONDING (47)- Secondary bonding(4)- Hydrogen Bonding (2)
I take immense pride in writing the 100th post on this blog. I am glad that I could continue writing throughout my pregnancy, after my daughter was
99.CHEMICAL BONDING (46)- Secondary bonding(3)- Hydrogen Bonding (1)
In this post we start discussing a type of secondary bonding, without which life would not be possible !! How is hydrogen bonding and life
98.CHEMICAL BONDING (45)- Secondary bonding(2)- Induced dipole- Induced dipole interactions.
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
97.CHEMICAL BONDING (44)- 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.CHEMICAL BONDING (43)- Metallic bonding(2).
As we discussed in the last post , the free electron gas model is not infallible. Almost 30 years after the electron gas model was

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.CHEMICAL BONDING (41)- 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

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.CHEMICAL BONDING (39)- Covalent Bonding(38) – Molecular Orbital Theory(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
