The bond length of \({\text{C - O}}\) bond in carbon monoxide is \(1.28 \stackrel{\circ}{\mathrm{A}}\) . The \({\text{C - O}}\) bond length in \(\mathrm{Fe}(\mathrm{CO})_{5}\) is:
1 \(1.15 \stackrel{\circ}{\mathrm{A}}\)
2 \(1.128 \stackrel{\circ}{\mathrm{A}}\)
3 \(1.118 \stackrel{\circ}{\mathrm{A}}\)
4 \(1.72 \stackrel{\circ}{\mathrm{A}}\)
Explanation:
Due to synergic bond formation, bond order decreases and bond length increases a little.

In which one of the following metal carbonyls, CO forms a bridge between metal atoms?
1 Here \(\mathrm{CO}\) acts as a Lewis base as well as Lewis acid
2 Here metal acts as Lewis base as well as Lewis acid
3 Here \(d \pi-p \pi\) back bonding takes place
4 Here \(p \pi-p \pi\) back bonding takes place
Explanation:
In metal carbonyls, paired d-orbital of central metal forms \(\pi\)-bond with vacant \(\pi^{*}\)-orbital of ligand \(\mathrm{CO}\).

Assertion : Zeise's salt is a \(\pi\)-bonded organometallic compound. Reason : The oxidation number of platinum in Zeise's salt is +2 .
1 Both Assertion and Reason are correct and Reason is the correct explanation of the Assertion.
2 Both Assertion and Reason are correct but Reason is not the correct explanation of the Assertion.
3 Assertion is correct but Reason is incorrect.
4 Assertion is incorrect but Reason is correct.
Explanation:
Zeise's salt is \(\mathrm{K}\left[\mathrm{PtCl}_{3}\left(\mathrm{C}_{2} \mathrm{H}_{4}\right)\right]\). In certain coordination complexes, the metal and ligand are involved in a type of bonding that specifically utilizes the \(\pi\)-electrons of the ligand. This uniquebonding interaction results in the formation of a \(\pi\)-bonded organometallic compound.The Pt is in +2 oxidation state. So the option (2) is correct.
