The correct order of ligands arranged in increasing field strength.

The correct order of ligands arranged in increasing field strength.
  1. \(\mathrm{F}^{-} < \mathrm{Br}^{-} < \mathrm{I}^{-} < \mathrm{NH}_3\)
  2. \(\mathrm{Br}^{-} < \mathrm{F}^{-} < \mathrm{H}_2 \mathrm{O} < \mathrm{NH}_3\)
  3. \(\mathrm{H}_2 \mathrm{O} < -\mathrm{OH} < \mathrm{CN}^{-} < \mathrm{NH}_3\)
  4. \(\mathrm{Cl}^{-} < -\mathrm{OH} < \mathrm{Br}^{-} < \mathrm{CN}^{-}\)

Solution

Experimental order $\mathrm{Br}^{-} < \mathrm{F}^{-} < \mathrm{H}_2 \mathrm{O} < \mathrm{NH}_3$
