Write the IUPAC names for the following complexes. (i) Na_(2)[Ni(EDTA)] (ii) [Ag(CN)_(2)]^(-) (iii)[Co(en)_(3)]_(2)(SO_(4))_(3) (iv) [Co(ONO)(NH_(3))_(5)]^(2+) (v)[Pt(NH_(3))_(2)Cl(NO_(2))]

Answer»

Solution :`(i) Na_(2)[Ni(EDTA)]` =Sodium Ethylenediaminetetraacetatonickelate (II)
(or)
Sodium `2,2.,2..,2...-` (ETHANE `-1,2`-diyldinitrilo) tetraacetonickelate
`(ii) [Ag(CN)_(2)]^(-)`=dicyanidoargentate (I) ion
`(iii)[Co(en)_(3)]_(2)(SO_(4))_(3)`= tris (ethylendediamine) COBALT (III) sulphate
`(iv) [Co(ONO)(NH_(3))_(5)]^(2+)`= PENTAAMMINENITRITO-`kO` Cobalt (III) ion
`(v)[Pt(NH_(3))_(2)Cl(NO_(2))]` =diamminedichloridonitrito-`KN` platinum `(II)`
