A) \[{{[Mn{{\left( CO \right)}_{6}}]}^{+}}\]
B) \[[Cr{{\left( CO \right)}_{6}}]\]
C) \[{{[V{{\left( CO \right)}_{6}}]}^{-}}\]
D) \[\left[ Fe{{\left( CO \right)}_{5}} \right]\]
Correct Answer: A
Solution :
[a] As positive charge on the central metal atom increases, the less readily the metal can donate electron density into the \[\pi *\] orbitals of CO ligand (donation of electron density into \[\pi *\] orbitals of CO result in weakening of \[C-O\] bond). Hence, the \[C-O\] bond would be strongest in\[{{[Mn{{(CO)}_{6}}]}^{+}}.\]You need to login to perform this action.
