Which of the following carbonyl will have the strongest C- O bond? 

  • (Mn(CO)6+

  • Cr(CO)6

  • V (CO)6-

  • Fe(CO)5

Answer

A.

(Mn(CO)6+

As the positive charge on the central metal atom increase, the less readily the metal can donate electron density into the anti - bonding pi-orbitals of CO ligand to weaken the C-O bond. Hence, the C-O bond would be strongest in Mn(CO)6+.
