IUPAC name of K3[Al(C2O4)3] is called

Question

IUPAC name of \(\mathrm{K}_{3}\left[\mathrm{Al}\left(\mathrm{C}_{2} \mathrm{O}_{4}\right)_{3}\right]\) is called

(a) potassium alumino-oxalato

(b) potassium aluminium (III) trioxalate

(c) potassium trioxalato aluminate (III)

(d) potassium tris (oxalato) aluminate (III)

Answer 1

Correct option is (d) potassium tris (oxalato) aluminate (III)

\(C_2 O ^{2-} _4\) is oxalato ion. In given complex oxidation state of aluminium is +3. So the IUPAC name is potassium trioxalatoaluminate(III).
