Question

Write IUPAC names of the following:
(i) K$_3$[AlF$_6$]
(ii) [Fe(H$_2$O)$_6$]Cl$_2$
(iii) [Co(NH$_3$)$_5$Cl]SO$_4$
(iv) K$_3$[Fe(CN)$_6$]

Hint:

Use fluorido, chlorido, cyanido, aqu(a) for ligand names; for complex anions, end the metal name with "-ate" (aluminate, ferrate) and give oxidation state in Roman numerals.

Answer 1

(i) \(\boxed{\text{Potassium hexafluoridoaluminate(III)}}\)
(ii) \(\boxed{\text{Hexaaquairon(II) chloride}}\)
(iii) \(\boxed{\text{Pentaamminechloridocobalt(III) sulfate}}\)
(iv) \(\boxed{\text{Potassium hexacyanidoferrate(III)}}\)
