A) \[{{[Fe{{(CN)}_{6}}]}^{4-}}\]
B) \[{{[Mn{{(CN)}_{6}}]}^{4-}}\]
C) \[{{[Co{{(N{{H}_{3}})}_{6}}]}^{3+}}\]
D) \[{{[Ni{{(N{{H}_{3}})}_{6}}]}^{2+}}\]
Correct Answer: D
Solution :
Complexes which use one ns, three np and two nd-orbital to form the sixhybrids are called outer-orbital complexes. So, find the electronic configuration of central metal ion. In this case alsois a strong ligand but electrons remain unpaired since only one orbital is left vacant in 3d. ThusYou need to login to perform this action.
