Q. Describe about Coordination compounds?
The complexes show a wide variety of physical and chemical properties which are quite different from normal salts. These differences arise due to the differences in their structures. In view of a special mode of bonding called coordination' being involved in their formation. They are also termed as coordination compounds. In this unit we shall briefly look at some of the basic definitions related to coordination compounds, familiarise you with different types of isomerism possible in them as well as the basic rules for naming these compounds. We shall then explain the formation of complexes in terms of different prevalent theories. However we shall not deal with some other aspects such as their thermody namic and kinetic stability and reaction mechanism. These cannot be dealt with satisfactory in such course. Finally we shall consider a few applications of complexes in different fields.
Chain, nuclear or skeleton isomerism: This form of isomerism arises because of the difference in the nature of the carbon chain (that is straight or branched) which makes the
Free-radical mechanism: Free-radical polymerisation is started by organic peroxide or other reagents that decompose to give free radicals.
