Given below are two statements : Statement I : [ Co ( NH ₃ )₆ ]³⁺ is a homoleptic complex whereas [ Co ( NH ₃ )₄ Cl ₂ ]⁺ is a heteroleptic complex. Statement II : Complex [ Co ( NH ₃ )₆ ]³⁺ has only one kind of ligands but [ Co ( NH ₃ )₄ Cl ₂ ]⁺ has more than one kind of ligands. In the light of the above statements, choose the correct answer from the options given below.
Options
- ABoth Statement I and Statement II are false
- BStatement I is true but Statement II is false
- CStatement I is false but Statement II is true
- DBoth Statement I and Statement II are true
Correct answer
D. Both Statement I and Statement II are true
Step-by-step solution
[ Co ( NH ₃ )₆ ]³⁺ is a homoleptic complex as only one type of ligands ( NH ₃ ) is coordinated with Co ³⁺ ion. While [ Co ( NH ₃ )₄ Cl ₂ ]⁺ is a heteroleptic complex in which Co ³⁺ ion is ligated with more than one type of ligands, i.e., NH ₃ and Cl ⁻ .
