Question

EAN of $Fe$ in $\left[Fe\right(C_2{O}_4{)}_3{]}^{3-}$ is :

• A. 27
• B. 24
• C. 35
• D. 29

Answer 1

Answer: (C)

35

E.A.N. = Atomic no. of central metal ion $-$ oxidation no. of central metal ion $+$ 2$\times$ coordination no. of central metal ion.

Atomic no. of Fe = 26

Oxidation no. of Fe in the given compound is = 3

Coordination no. = 6

E.A.N.$=26-3+2\times 6=35.$

Hence, option C is correct.
