Strongest C-O bond is present in

A

`[Mn(CO)_(6)]^(+)`

B

`[Cr(CO)_(6)]`

C

`[V(CO)_(6)]^(-)`

D

`[Fe(CO)_(5)]`

Text Solution

Verified by Experts

The correct Answer is:
A
The presence of positive charge on metal carbonyl would resist the flow of metal electrons charge to `pi^(+)` orbital of CO in the metal carbonyl cation would absorb at a higher frequency as compared to the absorption taking place in a neutral metal carbonyl .
