Multiple Choice QuestionsThe name of complex ion, [Fe(CN)6]3- is
hexacyanoiron (III) ion
hexacyanitoferrate (III) ion
tricyanoferrate (III) ion
tricyanoferrate (III) ion
Which of the following carbonyl will have the strongest C- O bond?
(Mn(CO)6+
Cr(CO)6
V (CO)6-
V (CO)6-
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+.
