Coordination Compounds Question 12
Question 12 - 30 January - Shift 1
Which of the following is correct order of ligand field strength?
(1) $CO<$ en $<NH_3<C_2 O_4^{2-}<S^{2-}$
(2) $S^{2-}<C_2 O_4^{2-}<NH_3<$ en $<CO$
(3) $NH_3<$ en $<CO<S^{2-}<C_2 O _{4-}^{2-}$
(4) $S^{2-}<NH_3<$ en $<CO<C_2 O_4^{2}$
Show Answer
Answer: (2)
Solution:
Formula: Spectrochemical series
The increasing order of field strength of ligands (according to spectrochemical series)
$ S^{2-}<C_2 O_4^{2-}<NH_3<en<CO $
