Which one of the following metal complexes is most stable?
Solution
Complex [Co(en)<sub>3</sub>]Cl<sub>2</sub> is most stable complex among the given complex compounds because more number of chelate rings are present in this complex as compare to others.<br><br>(1) [Co(en)(NH<sub>3</sub>)<sub>4</sub>]Cl<sub>2</sub> 1 chelate ring<br><br>(2) [Co(en)<sub>3</sub>]Cl<sub>2</sub> 3 chelate ring<br><br>(3) [Co(en)<sub>2</sub>(NH<sub>3</sub>)<sub>2</sub>]Cl<sub>2</sub> 2 chelate ring<br><br>(4) [Co(NH<sub>3</sub>)<sub>6</sub>]Cl<sub>2</sub> 0 chelate ring
