  • Complex compound are molecular compounds which rectain their identities even when dissolved in water. They do not give all the simple ions in solution but instead furnish complex ions with complicated structures. 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 structure, magnetic property, colour and electrical properties of complexes are explained by various theories. The oxidation number and coordination number and EAN of chromium in the following complex is : [Cr(C_(2)O_(4))_(2)(NH_(3))_(2)]^(-1)

    A
    `O.N.=+4, C.N.=4" and "EAN=36`
    B
    `O.N.=+3, C.N.=4" and "EAN=36`
    C
    `O.N.=-1, C.N.=4" and "EAN=33`
    D
    `O.N.=+3, C.N.=6" and "EAN=33`
