Which of the following ion does not follow EAN rule ?

A

`[Fe (CH)_(6)]^(4-)`

B

` [Ag (CN)_(2)]^(-)`

C

`[Pt (Cl)_(6) ]^(2-)`

D

None of these

Text Solution

Verified by Experts

The correct Answer is:
B
EAN = atomic number of central metal atom number of electron gained from ligands - oxidation state of central atom . According to EAN , for stable complex value of EAN = Atomic number of noble gas .
` [Ag (CN)_(2)]^(-),EAN = 47+2xx2-1=50`
