Which of the following is a correct increasing order of ligand field strength ?
Options
- AEDTA < C ₂ O ₄²⁻ < H ₂ O < en
- Ben < H ₂ O < EDTA < C ₂ O ₄²⁻
- CC ₂ O ₄²⁻ < H ₂ O < EDTA < en
- DH ₂ O < en < C ₂ O ₄²⁻ < EDTA
Correct answer
C. C ₂ O ₄²⁻ < H ₂ O < EDTA < en
Step-by-step solution
According to the spectrochemical series, the ligands are arranged in the increasing order of their crystal field splitting energy (CFSE) or ligand field strength as follows: I⁻ From the given options, the correct increasing order of ligand field strength is: C₂O₄²⁻ Answer: C ₂ O ₄²⁻ < H ₂ O < EDTA < en
