List of Ligands are given below from spectrochemical series, re-arrange in the order of increasing field strength
A. \(SCN^-\)
B. \(Cl^-\)
C. \(F^-\)
D. \(OH^-\)
E. \(CN^-\)
Choose the correct answer from the options given below:
Answer & explanation
Correct answer: option 3
The correct answer is Option (3) → A < B < C < D < E
Ligands arranged by increasing crystal field splitting form the spectrochemical series, found experimentally from the light absorbed by their complexes. Placing the five ligands in it, weakest first:
A. \( \ce{SCN-} \) — first. Just after \( \ce{I-} \) and \( \ce{Br-} \).
B. \( \ce{Cl-} \) — second.
C. \( \ce{F-} \) — third. After \( \ce{S^2-} \).
D. \( \ce{OH-} \) — fourth.
E. \( \ce{CN-} \) — last. A strong field ligand, near the end of the series.
