The correct order of decreasing bond lengths of CO, $$CO_2$$ and $$CO^{2-}_3$$ is:

A$$CO\,>\,CO_2\,>\,CO^{2-}_3$$
B$$CO^{2-}_3\,>\,CO_2\,>\,CO$$
Correct Answer
C$$CO_2\,>\,CO\,>\,CO^{2-}_3$$
D$$CO\,>\,CO^{2-}_3\,>\,CO$$

Solution

Bond length is directly proportional to bond order and bond order depends on number of bonds
$$\therefore CO$$ is $$C\equiv O$$
$$C{ O }_{ 2 }$$ is $$O=C=O$$
in $$C{ O }_{ 3 }^{ 2- }$$ bond order lies between single and double bond due to resonance
Hence bond length order will be
$$C{ O }_{ 3 }^{ 2- }>C{ O }_{ 2 }>CO$$
