Which of the following carbonyls will have the strongest C-O bond

A

`V(CO)_6^-`

B

`Fe(CO)_5`

C

`Mn(CO)_6^+`

D

`Cr(CO)_6`

Text Solution

Verified by Experts

The correct Answer is:
C
As +ve charge on the central metal atom increases, the less readily the metal can donate electron density into the `pi^*` orbitals of CO ligand to weaken the C-O bond. Hence the C−O bond would be strongest in `Mn(CO)_6^*`
