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.

here this complex exist with +3 oxidation state. The atomic number of cobalt is 27. The EAN of cobalt in Na3[Co(NO2)4Cl2] is 36. EAN=Z−X+Y Z is the atomic number of Co (27). X is the oxidation state of Co=3 Y is double of its coordination number= 12 EAN=X−Y+Z=27−3+12=36
According to your question, EAN is 37
so this complex is very unstable and can't be exist.. please correct if it is given in your book.. here charge on complex will be -3
yes sir thare is a mistake in the book
tqq sir😇
you welcome 👍🙂
