The correct order of ligands arranged in increasing field strength.

  1. Option A:

    Cl−<−OH<Br−<CN−\mathrm{Cl}^{-}<-\mathrm{OH}<\mathrm{Br}^{-}<\mathrm{CN}^{-}

  2. Option B:

    F−<Br−<I−<NH3\mathrm{F}^{-}<\mathrm{Br}^{-}<\mathrm{I}^{-}<\mathrm{NH}_{3}

  3. Option C:

    Br−<F−<H2O<NH3\mathrm{Br}^{-}<\mathrm{F}^{-}<\mathrm{H}_{2} \mathrm{O}<\mathrm{NH}_{3}

    Correct
  4. Option D:

    H2O<−OH<CN−<NH3\mathrm{H}_{2} \mathrm{O}<{ }^{-} \mathrm{OH}<\mathrm{CN}^{-}<\mathrm{NH}_{3}
