MECHANISM OF ORGANIC REACTIONS  Conversion of a chemical compound into another chemical compound is known as a chemical reaction. Organic reactions usually involve the fission and formation of covalent bonds. Organic reactions take place in accordance with general fundamental concepts of thermodynamics. Usually, the sequence and timing of these bonds breaking and bond forming processes are important in the study of these reactions. These processes may occur separately, for example, bond breaking may proceed bond formation or vice-versa resulting in a step-wise reaction. ARROW NOTATION (FORMALISM) Organic reactions usually involve the fission and formation of covalent bonds. The covalent bond is often represented as a dash (-) and the movement of a pair of electrons is shown by a curved arrow in fact, arrow formalism (notation) is very important for organic reactions. Arrows in chemical drawing have specific meanings. Just as it is important to learn the structural representa...
