Question

PZ (WH3)4 6. Write the formula for each of the following coordination compounds. a) Tetraammineplatinum(II) chloride PE (NH3)4 Ci - b) Sodium hexacyanoferrate(III) c) Tris(ethylenediamine)platinum(IV) sulfate d) Diamminesilver(I) nitrate e) Triamminetrithiocyanatorhodium(III) f) Potassium diaquadioxalatocobaltate(Ill) g) Ammonium pentachlorohydroxoferrate(III) 3+ k[co (H₂O), (C2O4)

Answer 1

* NOMENCLATURE Nou OF COORDINATION COMPOUNDS I Coordination compounds sphere may be cationic form or may anion form. If this sphere is cation then naming will end on that group which is ionizable. During the naming prefix like di tri should not be used with lonizable group. o ligands are arranged in alphabetical ordes without ондар — • Prefixes di, tri are not considered for comparison. • Along with metal its oxd" state should be mentioned

Ex :- [ Co (NH3 7 7 Uz hexaammine cobalt (II) chlorude nr 6/0)-3=0 n=3 {ver (H₂O) Qa] NO₂ tetrag aqua dichlorido chloro chromium (II) nitrate. prefixes like such ligand di, tri care ato already are present two time I of in the ligands present and if then bis 2 tris 3 EXT cr [cenz] tris (ethane 192- diamine) cromium (III) chloride However, if coordination naming will end sphere act on metal as atom sation with anion then suffix "ateg Ky [Fe(CN) Potassium hexacyano ferrate (I)

(a) [PE (NH3)4] U, (b) Na [Fe (CN)6] (C) [pt rew), 1 (504), (d) [Ag (NH3²2J NO (e) [Rh (NH} (SUN), I & K ochou (C2O4)2 ] (g) (NH4) [Fele, (OH) -
