The IUPAC name of `K_(3)[Ir(C_(2)O_(4))_(3)]` is

Options

A. potassium trioxalatoiridium(III)
B. potassium trioxalatoiridate(III)
C. potassium tris(oxalato)iridium(III)
D. potassium tris(oxalto)iridate(III)

Answer

B

Explanation

IUPAC name of `K_(3)[Ir(C_(2)O_(4))_(3)]` is potassium trioxalatoiridate (III)
Let O.S. of Ir = x
`:. 3(+1) + x + 3(-2)` = 0
x = `+3`
[O.S. of `K^(+) = +1 , O.S. of C_(2)O_(4)^(2-) = -2`]
