NEET
NEET 2016
Coordination Compounds
A
${NH_3 > CN^- > Br^- > C_6H^-_5 }$
18%
B
$CN^- > C_6H_5^- > Br^- > NH_3 $
56%
C
$ Br^- > CN^- > NH_3 > C_6H_5^-$
12%
D
$ CN^- > Br^- > C_6H_5^- > NH_3 $
14%
Solution:
Trans-effect: The intensity of trans-effect depend on increase in rate of substitution of the trans ligand.
$ F^{-} < NH_3 < Cl^{-} < Br^{-} < Ph^{-} < CH_{3}^{- } < CN^{-}$
