In which of the following coordinate compounds the central metal atom obeys the EAN rule.

A

All

B

`K_(3)[Fe(CN)_(6)]`

C

`K_(4)[Fe(CN)_(6)]`

D

`[Cu(NH_(3))_(4)]SO_(4)`

Text Solution

Verified by Experts

The correct Answer is:
C
E.A.N. of Fe in `K_(4)[Fe(CN)_(6)]`
= `24 (for Fe^(2+))+6 xx 2`
= `24+12=36-=[Kr]^(36)`
Thus E.A.N. rule is obeyed.
