Organic chemistry is that branch of chemistry which deals with the study of compounds of carbon with hydrogen (hydrocarbons), and their derivatives. Presently about five million organic compounds are know..

Chemical reactions mostly take place in solutions. Solution chemistry plays a very significant role in chemistry. All chemical substances are made up of either polar units (called ions) or non-polar units. The activity of these entities is more evident and pronounced in solution..

It is well known that a base is a substance that combines with an acid to form salt and water only. In the equations given below, the metal oxides behave as bases. ..

Organic chemistry is that branch of chemistry which deals with the study of compounds of carbon with hydrogen (hydrocarbons), and their derivatives. Presently about five million organic compounds are known. Since the synthesis of urea from ammonium thiocyanate, many organic comp..

Study of chemistry is important for the simple reason that, many chemicals find applications in almost all aspects of our daily lif..

There are just 26 alphabets in English language, but the number of words are innumerable. You have studied about the 115 known elements and how they are classified for systematic and comprehensive study. Thousands of compounds are born by various chemical reactions involving these elements. In earl..

Isocyanides are structural isomers of alkyl cyanides. In these compounds, the -C N group is linked to the alkyl or aryl group through N atom. The group is -NC. Thus they have the general formula is The isocyanide group also has a triple bond but constitutes a dipolar species in which n..

A story unfolds - Structure of atom : Let us right away meet those who scripted a "mighty story" of a "miniscule" atom. John Dalton (1766 - 1844) : Born in a poor family of a weaver in England, he rose to become a teacher and later a Principal of a school. In 1793, he left for Manche..

Organic compounds are isolated either from natural sources or from reaction mixtures. These compounds are seldom pure and are usually contaminated with small amounts of other similar compounds, which are found to exist together or formed during the reaction. In order to characterize them, it ..

With the rapid development of Chemistry and the discovery of new elements, it was necessary to develop a simple way to study and remember the numerous properties of the elements and their compounds. This gave rise to the necessity of classification of the elements into various group..
