Question

IUPAC name of $K_3\left[Fe\right(C_2{O}_4{)}_3]$ is:

• A. Potassium dioxalatoferrate(I)
• B. Potassium dioxalatoferrate(III)
• C. Potassium trioxalatoferrate(III)
• D. Potassium trioxalatoferate(II)

Answer 1

The correct option is C Potassium trioxalatoferrate(III)

$\underset{Potassium}{\underset{}{K_3}}\left[Fe\underset{Trioxolato}{\underset{}{(C_2{O}_4{)}_3}}\right]$

$n-6=-3$

Potassium trioxalato Ferrate(III) $=K_3\left[Fe\right(C_2{O}_4{)}_3]$
