JEE Main 12 Jan 2019 Morning Question 25
Question: The metal d- orbital that are directly facing the ligands in $ K _3[Co{{(CN)}_6}] $ are [JEE Main Online Paper Held On 12-Jan-2019 Morning]
Options:
A) $ d _{xy}and,{d _{x^{2}-y^{2}}} $
B) $ {d _{xy’}}d _{xz},and,d _{yz} $
C) $ {d _{x^{2}-y^{2}}},and,{d _{z^{2}}} $
D) $ {d _{xy’}}d _{yz},and,{d _{{z^{2.}}}} $
Show Answer
Answer:
Correct Answer: C
Solution:
- Due to presence of strong ligand $ (C{N^{-}}) $ pairing occurs in which two d-orbitals i.e., $ {d _{x^{2}-y^{2}}} $ and $ {d _{z^{2}}} $ directly face the -CN ligand.
