Question

Among the ligands NH3, en, CN- and CO the correct order of their increasing field strength, is : (A) NH3 < en < CN- < CO (B) CN- < NH3 < CO < en (C) en < CN- < NH3 < CO (D) CO < NH3 < en < CN-

Ligands can be arranged in a series in the orders of increasing field strength as given below :

I^{-} < B r^{-} < S^{2 -} < C l^{-} < N O_{3}^{-} < F^{-} < O H^{-} < EtO H < C_{2} O_{4}^{2 -} < H_{2} O

< NC S^{-} < E D T A < N H_{3} < e n < N O_{2}^{-} < C N^{-} < CO

Such a series is termed as spectrochemical series. It is an experimentally determined series based on the absorption of light by complexes with different ligands.

Q. Among the ligands $N H_{3}, e n, C N^{-}$ and CO the correct order of their increasing field strength, is :

$N H_{3} < e n < C N^{-} < CO$

$C N^{-} < N H_{3} < CO < e n$

$e n < C N^{-} < N H_{3} < CO$

$CO < N H_{3} < e n < C N^{-}$
