In the last two posts we discussed the VBT at length. We shall discuss its drawbacks and the hybridization theory in the next post.However, before proceeding to the hybridization theory , let us study the VSPER model first , which will help us understand the shape of the molecules explicitly. Valence shell electron pair repulsion model…

## 56. NATURE OF CHEMICAL BONDING (3)- Covalent Bonding(2)- VBT (2)

The Valence bond theory (VBT) is one of the theories which explains the formation of the covalent bond. It is based on the assumption that atomic orbitals overlap and form a bond.The electrons are shared between two atoms and the bond represents the region where the overlap occurs – the region with maximum electron density….

## 55. NATURE OF CHEMICAL BONDING (2)- Covalent Bonding(1)- VBT (1)

Bonding in molecules forms the basis of elucidating the structure of molecules , which in turn dictates the properties of substances.In this post we shall learn about second kind of primary bonds – The Covalent/Molecular Bonds. P2. THE COVALENT BOND. This bond is due to sharing of electron pairs between atoms.The atoms involved have same/similar…

## 54. NATURE OF CHEMICAL BONDING (1) – Types of bonds, Ionic bonds.

Chemistry encompasses the study of elements and the various species ( compounds/ions/complexes etc) which are formed from these elements. Thus, it is imperative to understand how atoms are held together in molecules , what forces hold these atoms together and what factors are responsible of specific orientations of molecules. Let us begin our discussion on…

## 13.SI Units.

As we know ,science is studied all around the world.Thus, it is essential that we have a standard system for measurements and have units for physical quantities which are accepted worldwide.Otherwise, it will be too difficult for people to keep a tab of different conventions and units and they will have to constantly convert quantities…

## 12.Chemistry & Mathematics VIII-Calculus(5)-Integration(2).

In the last post we studied what Integration means and some basic rules for finding integrals.I mentioned a term ‘Indefinite Integral’ in my last post.In this post let us discuss this term and other concepts related to Integration. There are two types of Integrals – A]Indefinite Integral. B]Definite Integral. A]Indefinite Integral – While specifying indefinite…

## 11.Chemistry & Mathematics VII-Calculus(4)-Integration(1).

Today I begin writing about the second part of calculus – INTEGRATION.In the earlier posts we discussed how differentiation helps us to divide our data into small components.This procedure helps us to get our results with exactitude.But it is also mandatory to collect these small pieces later and bring them together to get the final…

## 10.Chemistry & Mathematics VI-Calculus(3)-Differentiation(3).

Partial Differentiation. In this post I intend to discuss the concept of PARTIAL DIFFERENTIATION.We have already studied that for a function with one variable ‘y’ , y=f(x), the derivative f'(x) = dy/dx ⇒ represents the rate of change of ‘y’ as ‘x’ changes. But what if there are more than one variables? eg. In thermodynamics,…

## 9.Chemistry &Mathematics V-Calculus(2)-Differentiation(2).

In this post I intend to discuss the concept of differentiation in greater detail.In my last post we have already learned what derivatives are and why we need to learn this concept. Now let us try to find out exactly what a derivative function tell us with respect to graphs. A Basic point we need…
