Question

What is the EAN of [Al(C4O4)3]3- ? (A) 28 (B) 22 (C) 16 (D) 10

Tardigrade Admin · Accepted Answer

Effective atomic number EAN = Atomic number - oxidation number + 2 × coordination number For [ Al ( C 2 O 4)3]3- Z=13 ON =3 C N=6 ∴ EAN =13-3+2 × 6=22

Q. What is the EAN of $[A l (C_{4} O_{4})_{3}]^{3 -}$ ?

Effective atomic number EAN
= Atomic number - oxidation number $+$
$2 \times$ coordination number
For $[A l (C_{2} O_{4})_{3}]^{3 -}$
$Z = 13$
$ON = 3$
$CN = 6$
$∴$ EAN $= 13 - 3 + 2 \times 6 = 22$
