A) \[{{[Mn{{(CO)}_{6}}]}^{+}}\]
B) \[[Fe{{(CO)}_{5}}]\]
C) \[[Cr{{(CO)}_{6}}]\]
D) \[{{[V{{(CO)}_{6}}]}^{-}}\]
Correct Answer: B
Solution :
Greater the extent of \[d\pi -P\pi \]back bonding smaller will be the bond order of \[CO\]bond in metal carbonyls. In \[Fe{{(CO)}_{3}}\] there is maximum number of valence shell electrons (d-electrons), greatest chances of \[P\pi -d\pi \]back bonding, lowest bond order of \[CO\]bond.
