Question

Arrange the following complexes in the increasing order of conductivity of their solution
`[Co(NH_(3))_(3)Cl_(3)], [Co(NH_(3))_(4)Cl_(2)]Cl, [Co(NH_(3))_(6)]Cl_(3), [Cr(NH_(3))_(5)Cl] Cl_(2)`

Answer 1

All the complexes are of octahedral nature. The increasing order of conductivity is related to the number of ions that are available in solution. The correct order is:
`[Co(NH_(3))_(3)Cl_(3)] lt [Cr(NH_(3))_(4)Cl_(2)]Cl lt Co(NH_(3))_(5)Cl_(2) lt [Co(NH_(3))_(6)]Cl_(3)`
