In which of the following octahedral complexes of Co (at. no. 27), will the magnitude of Δo\Delta _o be the highest?

Multiple Choice Options

  • A [Co(CN)6]3−
  • B [Co(C2O4)3]3−
  • C [Co(H2O)6]3+
  • D [Co(NH3)6]3+

Step-by-Step Verified Solution

In octahedral complex the magnitude of Δo{\Delta _o} will be highest in a complex having strongest ligand. Of the given ligands CN−C{N^ - } is strongest so Δo{\Delta _o} will be highest for (Co(CN)6)3−.{\left( {Co{{\left( {CN} \right)}_6}} \right)^{3 - }}. Thus option (a)(a) is correct.
