Which among the following is a correct order of increasing field strength of ligands?
Options
- AI ⁻ < OH ⁻ < NH ₃ < S ²⁻
- BNH ₃ < OH ⁻ < I ⁻ < S ²⁻
- COH ⁻ < S ²⁻ < I ⁻¹ < NH ₃
- DI ⁻ < S ²⁻ < OH ⁻ < NH ₃
Correct answer
D. I ⁻ < S ²⁻ < OH ⁻ < NH ₃
Step-by-step solution
Spectrochemical series is given below: aligned & I ⁻ < Br ⁻ < S ²⁻ < CI ⁻ < OH ⁻ < C ₂ O ₄ ²⁻ < H ₂ O < NCS ⁻ < Py & < NH ₃ < en < NO ₂ ⁺ < CN ⁻ < CO aligned Order of increasing field strength of given ligands, I ⁻ < S ²⁻ < OH ⁻ < NH ₃
