Oxidation state of central metal atom in the given complex is:
\[
[Co(NH_3)_4(H_2O)_2]Cl_3
\]
Show Hint
- \( +2 \)
- \( +3 \)
- \( +1 \)
- \( +4 \)
The Correct Option is B
Solution and Explanation
\[ 4(NH_3) + 2(H_2O) + Co + 3Cl^- = 0 \] Step 2: \( NH_3 \) and \( H_2O \) are neutral ligands, so they contribute zero charge.
Chloride ion has a charge of \( -1 \) each. Total charge of three Cl\(^-\) is \(-3\).
\[ x + 0 - 3 = 0 \quad \Longrightarrow \quad x = +3 \]
Top Questions on Coordination Compounds
The Crystal Field Theory (CFT) of coordination compounds is based on the effect of different crystal fields (provided by the ligands taken as point charges) on the degeneracy of d-orbital energies of the central metal atom/ion. The splitting of the d-orbitals provides different electronic arrangements in strong and weak crystal fields. In tetrahedral coordination entity formation, the d-orbital splitting is smaller as compared to the octahedral entity.
