Question

Which of the following complexes do not follow EAN rule? (A)  [Fe(CN)6]4-  (B)  [Fe(CN)6]3-  (C)  Ni(CO)4  (D)  [PdCl4]2-

Tardigrade Admin · Accepted Answer

According to Sedgwick, EAN = atomic number of nearest noble gas Incase of [Fe(CN)6]3-, EAN=26-3+2× 6 =35 While, the atomic number of nearest noble gas is 36. Thus, it does not follow EAN rule.

Q. Which of the following complexes do not follow EAN rule?

$[F e (CN)_{6}]^{4 -}$

$[F e (CN)_{6}]^{3 -}$

$N i (CO)_{4}$

$[P d C l_{4}]^{2 -}$

According to Sedgwick, EAN = atomic number of nearest noble gas Incase of $[F e (CN)_{6}]^{3 -},$ $E A N = 26 - 3 + 2 \times 6$ $= 35$ While, the atomic number of nearest noble gas is 36. Thus, it does not follow EAN rule.
