What is EAN rule ?

Text Solution

Verified by Experts

‘Every central metal atom or ion in a complex has a tendency to acquire effective atomic number (EAN) of next inert gas. ’EAN of metal in- a complex = At. No. - Oxidation state `+2x x` Coordination number.
Ex.: EAN of Fe in `K_4 |Fe (CN)_6]` =(26 - 2) + 2 x 6 = 36 (At. No. of Krypton)
