Which of the following has longest \(C-O\) bond length ? (Free \(C-O\) bond length in \(CO\) is \(1.128\,\mathop A\limits^o .\))
1 \([Fe(CO)_4]^{2-}\)
2 \([Mn(CO)_6]^+\)
3 \(Ni(CO)_4\)
4 \([Co(CO)_4]^-\)
Explanation:
As the negative charge on metal carbonyl complex increases back pi bonding increases and hence the bond length of \(\mathrm{C}-O\) bond increases while the bond length of metal-carbon bond decreases. Hence. [Fe(CO), \(] ^{2-} {\text { has longest } C-O \text { bond length }}\) among the given complexes. The correct order of bond length of the given complexes is \(\left[\mathrm{Mn}(\mathrm{CO})_{6}\right]^{+} < { \left[\mathrm{Ni}(\mathrm{CO})_{4}\right]}<\left[\mathrm{Co}(\mathrm{CO})_{4}\right]^{-}<\left[\mathrm{Fe}(\mathrm{CO})_{4}\right]^{2-}\)

The hybridization involved in complex \([Ni(CN)_4]^{2-}\) is (At. No. \(Ni = 28\))
1 \(sp^3\)
2 \(d^2sp^2\)
3 \(d^2sp^3\)
4 \(dsp^2\)
Explanation:
\(\left[\mathrm{Ni}(\mathrm{CN})_{4}\right]^{2-}\) oxidation state of Ni is \(+2\) \(x-4=2\) \(x=+2\)

The name of complex ion, \([Fe(CN)_6]^{3-}\) is
1 hexacyanitoferrate \((III)\) ion
2 tricyanoferrate \((III)\) ion
3 hexacyanidoferrate \((III)\) ion
4 hexacyanoiron \((III)\) ion.
Explanation:
When complex-ions is an anion, the name of the metal ends with the suffix-ate along with its oxidation number in the complex-ion. \(\left[\mathrm{Fe}(\mathrm{CN})_{6}\right]^{3-}=\) Hexacyanidoferrate \((III)\) ion
