The order of increasing CO stretching frequencies in $[Co(CO)_4]^-, [Cu(CO)_4]^+, [Fe(CO)_4]^{2-} and [Ni(CO_4)]$ is
Updated On: Oct 1, 2024
- $[Cu(CO)_4]^+ < [Ni(CO)_4] < [Co(CO)_4]^- < [Fe(CO)_4]^{2-}$
- $[Fe(CO)_4]^{2-} < [Co(CO)_4]^- < [Ni(CO)_4] < [Cu(CO)_4]^+$
- $[Co(CO)_4]^- < [Fe(CO)_4]^{2-} < [Cu(CO)_4]^+ < [Ni(CO)_4]$
- $[Ni(CO)4] < [Cu(CO)_4]^+ < [Co(CO)_4]^- < [Fe(CO)_4]^{2-}$
Hide Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
