Question

answer the following questions about the transition metals complexes with the chemical formulas [Cr(NO2)6]4-and [Cr(NH3)6]2+. Assume nitrogen is the donor atom in both complexes.

A.Give the names of those two transition metal complexes.

B.How many d electrons do the transition metal complexes have (hint: it is the same number for both of them!)?

C.Construct d-orbital splitting diagrams for a low-spin and high-spin complex with the d electron count determined in Question B.

D.Would either the low-spin or high-spin configuration result in a paramagnetic complex?

E.One of the complexes is purple while the other is yellow. Which chromium complex is which color? Justify your answer for full credit and identify which color the complex will absorb based on its color
