Question

Transition metal complex with highest value of crystal field splitting (Δ_o) will be ______.

पर्याय

• [Cr(H₂O)₆]³⁺

• [Mo(H₂O)₆]³⁺

• [Fe(H₂O)₆]³⁺

• [Os(H₂O)₆]³⁺

Answer 1

Transition metal complex with highest value of crystal field splitting (Δ_o) will be `bbunderline([Os(H_2O)_6]^(3+))`.

Explanation:

• Δ_o​ increases with the oxidation state of the metal and the size of the metal ion.
• Osmium (Os) is the heaviest metal in the +3 oxidation state among the options, resulting in the largest crystal field splitting energy (Δ_o​).
• Hence, [Os(H₂O)₆]³⁺ has the highest Δ_o​ compared to the other complexes.
