  2. B \(CN^- > C_6H_6^- > Br^- > NH_3\)
  3. C \(Br^- > CN^- > NH_3 > C_6H_5^-\)
  4. D \(CN^- > Br^- > C_6H_5^- > NH_3\)
Verified Solution

Answer & Solution

Correct Answer

(B) \(CN^- > C_6H_6^- > Br^- > NH_3\)

Step-by-step Solution

Detailed explanation

Trans-effect: The intensity of trans-effect depend on increase in rate of substitution of the trans ligand. \(\mathrm{F}^{-} < \mathrm{NH}_{3} < \mathrm{Cl}^{-} < \mathrm{Br}^{-} \)\(< \mathrm{Ph}^{-} < \mathrm{CH}_{3}^{-} < \mathrm{CN}^{-}\)
