The number of geometric isomer of the complex Cr(NH3)3Cl3 is
Two isomers, cis and trans; in cis-isomer all NH3 groups occupy one face of the octahedron and hence Cl atoms occupy another (opposite face).
Following Sidwick’s rule of EAN, Co2(CO)x will be
In the reactions
two isomers of the product are obtained. The initial complex is
On treatment of [Ni(NH3)4]2+ with concentrated HCl, two compounds I and II having the same formula, Ni(NH3)2Cl2 are obtained. I can be converted into II by boiling with dilute HCl. A solution of I reacts with oxalic acid to form [Ni(NH3)2(C2O4) whereas II does not react. Point out the correct statement of the following
