The correct increasing order of trans-effect of the following species is

Options

  1. ANH3>CN−>Br−>C6H5−{NH}_{3} > {CN}^{-} > {Br}^{-} > {C}_{6}{H}_{5}^{-}
  2. BCN−>C6H5−>Br−>NH3{CN}^{-} > {C}_{6}{H}_{5}^{-} > {Br}^{-} > {NH}_{3}
  3. CBr−>CN−>NH3>C6H5−{Br}^{-} > {CN}^{-} > {NH}_{3} > {C}_{6}{H}_{5}^{-}
  4. DCN−>Br−>C6H5−>NH3{CN}^{-} > {Br}^{-} > {C}_{6}{H}_{5}^{-} > {NH}_{3}

Correct answer

B. CN−>C6H5−>Br−>NH3{CN}^{-} > {C}_{6}{H}_{5}^{-} > {Br}^{-} > {NH}_{3}

Step-by-step solution

The trans effect is the increased lability of ligands that are trans to certain other ligands, which can thus be regarded as trans-directing ligands. It is attributed to electronic effects and it is most notable in square planar complexes, although it can also be observed for octahedral complexes.

CN−>C6H5−>Br−>NH3{CN}^{-} > {C}_{6}{H}_{5}^{-} > {Br}^{-} > {NH}_{3}
