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
