please answer the follwing question and please show your work

it is important to explain by using Tanabe Sugano

Upon completion of the following reaction, the "colorless" (in real life, actually very pale purple) Fe(H_20)6^3+ complex is converted into a bright yellow complex, FeX_6^3". Xis a monodentate ligand with a charge of-1. Fe(H_20)_6(N0_3)3 + 6KX K_3FeX_6 + 3KN0_3 Is X a strong-field ligand or a weak-field ligand? Explain your answer using the appropriate Tanabe-Sugano diagram. Based on the spectrochemical series, suggest a possible identity for X.

Explanation / Answer

I- < Br- < SCN- < Cl- < F- OH- , ONO- < OH2 < NCS- < NCCH3 < NH3 , py < NO2- < CN- , NO , CO , THIS PARTIAL SPECTROCHEMICAL SERIES.

since X substitue the strong field ligand so it is even more strong field than NO2- .

b. this could be CN-
