Although the Lewis structures give an idea of the valence electrons around the atom, in reality it does not precisely locate the position of the electrons in the chemical bond. The behaviour of electrons in molecules and compounds is made by the valence bond theory in terms of the quantu..

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 ..

Introduction - Biomolecules are complex organic molecules. These molecules form the basic structural constituent of a living cell. The organic compounds such as amino acids, nucleotides and monosaccharides serve as building blocks of complex biomolecules. The important biomolecules are pr..

Introduction - The branch of chemistry, which deals with energy changes during various physical processes and chemical reactions, is called chemical energetics. All chemical reactions are normally accompanied by energy changes. These energy changes take place because energy is n..

>When a mixture of hydrogen and chlorine is exposed to sunlight, it reacts violently. This reaction is believed to occur by the following mechanism. This is the first step. It is called the initiation step. These chlorine atoms are very reactive and react with hydrogen molecule (step 2). ..
