Question

Given below are two statements:
Statement I: Both [Co(NH₃)₆]³⁺ and [CoF₆]^3- complexes are octahedral but differ in their magnetic behaviour.
Statement II: [Co(NH₃)₆]³⁺ is diamagnetic whereas [CoF₆]^3- is paramagnetic.
In the light of the above statements, choose the correct answer from the options given below:

• A. Both Statement I and Statement II are true
• B. Both Statement I and Statement II are false
• C. Statement I is true but Statement II is false
• D. Statement I is false but Statement II is true

Answer 1

The Correct Option is A

- A homoleptic complex contains identical ligands, e.g., $[Co(NH_3)_6]^{3+}$,

with only $NH_3$. 

- A heteroleptic complex contains different ligands, e.g., $[Co(NH_3)_4Cl_2]^+$,

with $NH_3$ and $Cl^-$. Both statements are true.
