Chemistry Questions & Answers (Compiled from UPSC, SSC ,PSC ,IBPS previous question papers)

  • Which of these statements about [Co(CN)6] is true:-

  • [Co(CN)6] has four unpaired electrons and will be in a low-spin configuration.
  • [Co(CN)6] has four unpaired electrons and will be in a high spin configuration.
  • [Co(CN)6] has no unpaired electrons and will be in a high-spin configurtion.
  • [Co(CN)6] has no unpaired electrons and will be in a low-spin configuration.
  • Explanation:

    [Co(CN)6]

    Co+3 = 3d6 4s0 4p0

    in presence of strong field ligand, pairing of
    electrons occurs so in this complex no unpaired
    electron is present and it is low spin complex.
