...see part (v).....how ONO can be ahead coz it starts with N....and NH3 starts with A....so ammine should be ahead and nitrito-O should follow it....???

Question S using IIJPAC norms write the tormulas for the following: (i) Tetrahydroxozincate(ll) (ii) Potassium tetrachloridopalladate(ll) (iii) Diamminedicnloridoplatinum(ll) (iv) Potassium tetracyanonickelate(ll) (v) Pentaamminenitrito-o-cobalt(lll) (vi) Hexaamminecobalt(lll) sulphate (vii) Potassium tri(oxalato)chromate(lll) (viii) Hexaammineplatinum(lV) (ix) Tetraöromidocuprate(ll) (x) Pentaamminenitrito-N-coöalt(lll) Answer 9.6: (ii) K2[PdC141 (v) [CO(ONO) (Vi) (S04)3 (Vii)

No, while writing the molecular formula for coordination compounds, we write the central atom first followed by negative ligands, neutral ligands and then positive ligands.

Thus, as ONO- is a negative ligand and NH3 is a neutral ligand, the former is placed first.
