Question

Find the order of field strength
\( \text{CN}^- \), \( \text{SCN}^- \), \( \text{NCS}^- \), \( \text{S}^{2-} \), \( \text{OH}^- \)

Hint:

A simplified version of the spectrochemical series to memorize is:
\( \text{I}^- < \text{Br}^- < \text{Cl}^- < \text{F}^- < \text{OH}^- < \text{H}_2\text{O} < \text{NH}_3 < \text{en} < \text{CN}^- < \text{CO} \).
Use donor atom types (Halogen \( < \) O \( < \) N \( < \) C) as a rule of thumb.
