Question

Which of the following is the correct configuration of the complex $[RhCl_6]^{3-}$ ?

• A. High spin $t^{4}_{2g}\,e^{2}_{g}$
• B. Low spin $t^{6}_{2g}\,e^{0}_{g}$
• C. Low spin $t^{3}_{2g}\,e^{3}_{g}$
• D. High spin $t^{5}_{2g}\,e^{1}_{g}$

Answer 1

Answer: (B)

Low spin $t^{6}_{2g}\,e^{0}_{g}$

Answer 2

Elements of $4d$ and $5d$ series are more prone to spin pairing therefore they from low spin complexes
