Q. The most stable complex among the following is

Coordination Compounds

Solution:

Stability of a complex depends upon the strength of ligand and charge of the central metal ion.
Stability of complex $\propto$ strength of ligand $∝$ charge of central metal ion.
Among the given complexes, in $[Ni(CN)_4]^{3-},$ the charge of central metal ion is highest, i.e., + 1 while CO is the strongest field ligand. Hence, $[Fe(CO)_5]$ is the most stable complex among the given complexes.
