Text Solution

Verified by Experts

The correct Answer is:
B
CO bond order`prop(1)/("Extent of back bonding "(Mto CO))`
Correct sequence of CO bond order:
`underset(("CO bond order "gt3.0))(H_(3)B larr CO) gt underset(B.O.=3.0)(CO) gt underset(("CO bond order " lt 3.0))(Fe(CO)_(5)) gt underset(("CO bond order "lt 3.0))([Mg(CO)_(5)]^(-))`
