Given below are two statements : Statement I : Complexes such as [Fe(C₂O₄)₃]³⁻ and [Co(en)₃]³⁺ are classified as heteroleptic complexes because they contain bidentate ligands. Statement II : In homoleptic complexes, the central metal atom or ion is bound to only one kind of donor group. In the light of the above statements, choose the correct answer from the options given below.
Options
- AStatement I is true but Statement II is false
- BBoth Statement I and Statement II are false
- CBoth Statement I and Statement II are true
- DStatement I is false but Statement II is true
Correct answer
D. Statement I is false but Statement II is true
Step-by-step solution
Statement I is false because [Fe(C₂O₄)₃]³⁻ and [Co(en)₃]³⁺ contain only one type of ligand (oxalate and ethylenediamine, respectively). Complexes in which the central metal atom or ion is bound to only one kind of donor group are called homoleptic complexes, regardless of whether the ligands are monodentate or bidentate. Statement II is true as it correctly defines homoleptic complexes, where the central metal atom or ion is bound to only one kind of donor group. Therefore, Statement I is false but Statement II is
