Question

Given below are two statements:

Statement I: Both [Co(NH₃)₆]³⁺ and [CoF₆]³⁻ complexes are octahedral but differ in their magnetic behavior.

Statement II: [Co(NH₃)₆]³⁺ is diamagnetic whereas [CoF₆]³⁻ is paramagnetic.

In the light of the above statements, Choose the correct answer form the options given below:

Options

• Statement I is true but Statement II is false.

• Statement I is false but Statement II is true.

• Both Statement I and Statement II are true.

• Both Statement I and Statement II are false.

Answer 1

Both Statement I and Statement II are true.

Explanation

[Co(NH₃)₆]³⁺ and [CoF₆]³⁻ complexes are octahedral. [Co(NH₃)₆]³⁺ is diamagnetic due to its paired electrons \[\ce{(t^6_{2g} e^0_g)}\]. [CoF₆]³⁻ is paramagnetic due to its four unpaired electrons.

Hence, given both the statements are true.
