Choose the correct answer from the options given below:
Given below are two statements :
Statement I: Both $$[\mathrm{Co}(\mathrm{NH}_3)_6]^{3+}$$ and $$[\mathrm{CoF}_6]^{3-}$$ complexes are octahedral but differ in their magnetic behaviour.
Statement II: $$[\mathrm{Co}(\mathrm{NH}_3)_6]^{3+}$$ is diamagnetic whereas $$[\mathrm{CoF}_6]^{3-}$$ is paramagnetic.
In the light of the above statements, choose the correct answer from the options given below:
Given below are two statements :
Statement I : $$[\mathrm{Co}(\mathrm{NH}_3)_6]^{3+}$$ is a homoleptic complex whereas $$[\mathrm{Co}(\mathrm{NH}_3)_4 \mathrm{Cl}_2]^{+}$$ is a heteroleptic complex.
Statement II : Complex $$[\mathrm{Co}(\mathrm{NH}_3)_6]^{3+}$$ has only one kind of ligands but $$[\mathrm{Co}(\mathrm{NH}_3)_4 \mathrm{Cl}_2]^{+}$$ has more than one kind of ligands.
In the light of the above statements, choose the correct answer from the options given below.
