Question

The IUPAC name of $K_3[Ir(C_2O_4)_3]$ is

• A. potassium trioxalatoidium(III)
• B. potassium trioxalaoiridate(III)
• C. potassium tris(oxalato)iridium(III)
• D. potassium tris(oxalato)iridate(III)

Answer 1

Answer: (B)

potassium trioxalaoiridate(III)

Answer 2

IUPAC name of $K_3[Ir(C_2O_4)_3]$ is potassium trioxalatoiridate (III) Let O.S. of Ir - $x$ $\therefore$ 3(+ 1) + $x$ + 3(-2) = 0 $x$ = + 3 [O.S. of $K^+$ = +1. O.S. of $C2^{2-}_4$ = -2]
