Time management is very much important in IIT JAM. The eduncle test series for IIT JAM Mathematical Statistics helped me a lot in this portion. I am very thankful to the test series I bought from eduncle.

keep in mind also one thing about electroneutrality principle that in the transition metal series the nickel,copper etc mainly prefer to take coordination number 4..because electrons in d orbitals increases from left to right in transition metal series and more CN means more ligand .so electron density on metal ion is more...so stability decreases
![eduncle-logo-app]()
if suppose CN 6 is there with nickel complex..then it is possible only when it is attached with more electronegative ligand like H20 ,NH3,F etc...so that EN atom in this ligand attract the pair of electrons and stabilises the complex
![eduncle-logo-app]()
Example Ni(h20)6 2+,Ni(nh3)6 2+ ,NiF6 4- exist but Ni(Cl)6 4- doesn't exist...so this is the application of electroneutrality principle...it can say the existence of some complex
