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


Correct option is

I cis, II trans; both square planar

Only cis isomer can easily form a chelate ring with oxalate group; the trans isomer cannot form a chelate ring. Both are square planar.



Octahedral complex of Cr(III) will be


For the correct assignment of electronic configuration of a complex, the valence bond theory often requires the measurement of


Mn2+ forms a complex with Br ion. The magnetic moment of the complex is 5.92 B.M. What would be the probable formula and geometry of the complex?
