    The primary and secondary valencies of the central metal ion in the complex [Co(NH_(3))_(6)]Cl_(3) respectively are

    Complex compounds are molecular compounds which retain their indentities even when dissolved in water. They do not give all the simple ions in solution but instead furnish complex ions. The complex compounds are often called coordination compounds because certain groups called ligands are attached to the central metal ion by coordinate or dative bonds. Coordination compounds exhibit isomerism, both structural and stereoisomerism. The struculre, magnetic property, colour and electrical properties of complexes are explained by various theories. Arrange the following compounds in order of of their molar conductance : i) K[Co(NO_(2))_(4)(NH_(3))_(2)] ii) [Cr(ONO)_(3)(NH_(3))_(3)] iii) [Cr(NO_(2))(NH_(3))_(5)]_(3)[Co(NO_(2))_(6)]_(2) iv) Mg[Cr(NO_(2))_(5)(NH_(3))]
