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…

48.THE PERIODIC TABLE – Is it totally accurate?

The last few posts were completely dedicated to studying the periodic table – A table of elements, which is very fundamental to many sciences like chemistry, physics and material science. This table is at the core of almost everything that is tangible in the universe.It took great effort to develop the entire table, to study…

46.THE PERIODIC TABLE – Electronegativity,EN( χ).

We introduce ourselves to a new concept in this post , which is quiet pertinent to the study of chemical bonds and reactions – Electronegativity . Let us discuss all about this new property , its trends and its use in the study of chemistry. Electronegativity(χ) –  Electronegativity(EN) is a concept , which describes an atom’s…

45.THE PERIODIC TABLE – Electron Affinity (EA).

We begin discussing one more important property of elements in this post – The Electron Affinity(EA). Electron Affinity (EA) – As the name suggests, this parameter talks about how much affinity a species has for electrons. Definition – Electron affinity of an atom /molecule is  the amount of energy released , when an electron is added to each atom…
