Question: Among the following species the one which causes the highest $ CFSE,{\Delta_{o}} $ as a ligand is:
Options:
A) $ C{N^{-}} $
B) $ ~NH_3 $
C) $ {F^{-}} $
D) CO
Show Answer
Answer:
Correct Answer: D
Solution:
Following is the order of increasing value of $ {\Delta_{o}} $ for the ligands.
$ {I^{-}}<B{r^{-}}<C{l^{-}}<{F^{-}}<H_2O<Py=NH_3<en< $
$ NO_2^{-}«C{N^{-}}<CO $
