1.	According to werner, the arrangement of 6 groups around the metal centre within the co-ordination sphere can lead to three possible geometries (For Q. 1 and Q. 2) : planar hexagon, trigonal prism and octahedral. For a particular geometry, if the groups (i.e. ligands) are arranged in different ways then the possibility of geometrical isomerism will arise.

Answer» <P>P, Q Q, R Q, S P,S Solution :Mabcd can SHOW G.I. if PLANAR. ALSO, it can show O.I. if tetrahedral.
