Among the ligands NH₃, en, CN– and CO, the correct order of their increasing field strength, is
A.CO < NH₃< en < CN–
B.NH₃< en < CN–< CO✓ Correct
C.CN–< NH₃< CO < en
D.en < CN–< NH₃ < CO
Explanation
We can solve this question using the spectrochemical series in which the ligands are arranged in the increasing order of the strength of the crystal field. Hence, the order will be - 3 NH <en<CN <CO Hence, the correct answer is option (b)
