MCQ
$EAN$ of $Mg$ is ... in $[Mg(EDTA)]^{2-}$
- A$16$
- B$20$
- ✓$22$
- D$18$
✓
Answer
Correct option: C.
$22$
c
$E.A.N. =$ Atomic no. of central metal ion $-$ oxidation no. of central metal ion $+$ $2^{\times}$coordination no. of central metal ion.
$E.A.N. =$ 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. $=26-3+2 \times 6=35$.
