According to werner s theory of coordination compounds, there are two types of valencies in coordination compounds. Are you ready to learn the important postulates of this theory. Primary valence equals the metals oxidation number. Alfred werner 18661919, a swiss chemist was the first to formulate his ideas about the structures of coordination compounds. Chapter 24 chemistry of coordination compoundswerners theory. A very famous scientist werner s in the year 1823 put forward his theory of coordination compounds which describes the formation and structure of complex compounds which is later termed as werners theory of coordinate compounds due to this theory he is awarded by nobel prize and he is also called the father of coordination chemistry. Valence bond theory and its application to complexes of coordination numbers 4 and 6.
Werner postulated that metals exhibit two types of valencies. These are nonionisable valencies, satisfied by ligands and determines the coordination number of the metal atom. Werner was the first inorganic chemist to be awarded the noble prize for chemistry in 19. Werners theory of coordination compounds self study point. A brief idea about chelate effect and labile and inert complexes. Werner proposed the concept of a primary valence and a.
