Types of Bond cleavage Homolytic cleavage: Homolytic fission is where each atom of the bond keeps an electron each resulting in species called free radicals. R−X→R∙+X∙ Homolytic cleavage occurs generally in the gas phase or in solution in non-polar Solvents and is catalyzed by ultraviolet light or high temperature of or by radical initiators such as Read more about Fundamental Concepts of Inorganic Reaction Mechanisms I[…]

When mono substituted benzene is subjected to further substitution, di-substituted products are formed. They are Ortho, para and meta. The product which is formed more predominately depends on nature of the substituents already present in the benzene ring. This is known as direct influence of substituents. Ortho and para directing groups: They direct the incoming Read more about Directive influence of functional groups in mono substituted benzene[…]
