57. NATURE OF CHEMICAL BONDING (4)- Covalent Bonding(3)- VESPR model(1).

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…

53.TYPES OF ORGANIC FORMULAE -(3) – Structural Formulae.

In this post we shall study how to draw structural formulae for different organic molecules. Understanding the structural representation of molecules is very important in our later course of study. We shall study in detail the stereochemistry( i.e spatial arrangement) of molecules in upcoming posts , and one can only grasp the topic if the…

52.TYPES OF ORGANIC FORMULAE – (2)- Molecular formula.

After having studied the empirical formula in the previous post , let us now move forward and learn what is a molecular formula for a molecule and how to calculate it.We shall solve some numerical problems later , before concluding this post. Molecular Formula – A chemical formula that shows the total number and kinds…

51. TYPES OF ORGANIC FORMULAE-(1) – Empirical formula.

Let us dedicate this post in understanding the empirical formula in organic chemistry. In successive posts, we shall study other types of formulae.It is imperative that one understands these correctly as they form the basis of understanding the structures of organic molecules. Empirical Formula – This is the simplest formula that shows the simplest whole…

50.ORGANIC CHEMISTRY- Classification.

It gives me immense gratification to be writing this 50th post exactly after one year , since I started writing this blog.It gives me even more pleasure to be writing about a subject, in which I completed my Masters degree – Organic Chemistry! So, lets continue our discussion on organic compounds in this post. Before we start classifying organic…

49. ORGANIC CHEMISTRY -Introduction.

Lets begin our discussion on one of the most profound branches of chemistry ,which deals mainly with only one element and its compounds, from the periodic table – CARBON! Organic chemistry is synonymous to the element CARBON. Organic chemistry is a branch of chemistry that studies exclusively structure, properties ,reactions of organic materials and compounds…
