Which of the following are not postulates of Werner? (P) In co-ordination compounds, metals show two types of linkage (valencies) primary and secondary (Q) The primary valencies are normally ionisable. These are satisfied by negative ions. (R) The secondary valency is equal to the co-ordination number and is fixed for a metal (S) The ions/groups bound by the primary and secondary linkages to the metal have characteristic spatial arrangements corresponding to different coordination numbers (T) Octahedral, Tetrahedral and Square planar geometrical shapes are more common in co-ordination compounds of transition metals
