Question

Write IUPAC names of the following:
(i) K$_2$[HgI$_4$]
(ii) [Cu(NH$_3$)$_4$]SO$_4$
(iii) K$_3$[Al(C$_2$O$_4$)$_3$]
(iv) [Cr(CO)$_6$]

Hint:

For anionic complexes, use metal name ending in "\,-ate" (mercurate, aluminate). Neutral ligands: \(\mathrm{NH_3}\) = ammine, CO = carbonyl; give oxidation state in Roman numerals.

Answer 1

(i) \(\boxed{\text{Potassium tetraiodidomercurate(II)}}\)
(ii) \(\boxed{\text{Tetraamminecopper(II) sulfate}}\)
(iii) \(\boxed{\text{Potassium tris(oxalato)aluminate(III)}}\)
(iv) \(\boxed{\text{Hexacarbonylchromium(0)}}\)
