The correct order of M – C p-bond strength in given metal carbonyl is : -
A
[Fe(CO)4]2–> [Co(CO)4]–> [Ni(CO)4]
B
[Ni(CO)4] > [Co(CO)4]–> [Fe(CO)4]2–
C
[Fe(CO)4]2–> [Ni(CO)4] > [Co(CO)4]–
D
[Ni(CO)4] > [Co(CO)4]– = [Fe(CO)4]2–
Answer
Fe(CO)<sub>4</sub>2–> Co(CO)<sub>4</sub>–> Ni(CO)<sub>4</sub>
Explanation
Solution
More the (-) ve charge density on metal ,more the strength of M – C p – bond.
