Organic Chemistry - Some Basic Principles and Techniques

In this section we will be studying Organic Chemistry Basics. Meaning we will have a brief discussion on the basic principles and techniques of Organic Chemistry. Study the following topics to know more about Organic Chemistry:

Organic Chemistry - The Definition -

We have already studied the definition of Organic Chemistry which is the scientific study of carbon compounds, these carbon compounds are basically hydrocarbons and their derivatives. These compounds are extracted from plants and animals.

Carbon Shapes of the Organic Compounds -

In this, we study catenation, which is defined as the atoms of an element that links to form chains and rings via itself and is thus known as the self-linking element.

Further, in this topic, we also learn about ‘Tetravalency’ which means that the carbon compound is satisfied by forming the carbon, hydrogen, or other atoms.

Structural Representation of Organic Compounds -

There are basically three structures of Organic Compounds formation:

Complete Structural Formula
Condensed Structural Formula
Bondline Structural Formula

Classification of Organic Compounds -

Organic Compounds can be classified into the following:

Acyclic or Open Chain Compounds & Alicyclic or Closed Chain or Ring Compounds
Aromatic Compounds
Heterocyclic Aromatic Compounds

Nomenclature of Organic Compounds -

The nomenclature follows the suggestions of IUPAC in naming the organic compounds, carbocations, etc.

Methods of Purification of Organic Compounds -

Following are the methods of purification of organic compounds:

Simple crystallization
Fractional crystallization
Sublimation
Simple distillation
Fractional distillation
Steam distillation
Azeotropic distillation
Chromatography

Hope this article benefitted the students with required insights about Organic Chemistry. We have discussed the definition of Organic Compounds, the topics covered in the chapter of Organic Compounds, and the basic principles and bases of Organic Compounds.
