In the complex $\Fe(CO)_5$, what is the oxidation state of iron?

What is the coordination number of iron in $\Fe(CO)_5$?

Which of the following is the correct structure of $\Fe(CO)_5$?

Which of the following molecules has the longest $\rm{C-O}$ bond length? (Free $\rm{C-O}$ bond length in $\rm{CO}$ is 1.128 \mathop {\rm{A}}\limits^\rm{o})

Arrange the following molecules in increasing order of their $\rm{C-O}$ bond length: $\rm{CO}$, $\rm{CO_2}$, $\rm{CH_3OH}$, $\rm{HCO_2^-}$ (formate ion).

Which of the following has the shortest $\rm{C-O}$ bond length?

In the carbonate ion ($\rm{CO_3^{2-}}$), what is the approximate $\rm{C-O}$ bond length? (Given: $\rm{C-O}$ single bond = 1.43 Å, $\rm{C=O}$ double bond = 1.23 Å)

The $\rm{C-O}$ bond length in methanol ($\rm{CH_3OH}$) is longer than the $\rm{C-O}$ bond length in formaldehyde ($\rm{H_2CO}$). Why?
