Vedclass · Answer

(D) The $EAN$ (Effective Atomic Number) is calculated using the formula:
$EAN = (	ext{Atomic number} - 	ext{Oxidation state} + 2 	imes 	ext{Coordination number})$
For $Ni(CO)_4$:
Atomic number of $Ni = 28$
Oxidation state of $Ni = 0$ (since $CO$ is a neutral ligand)
Coordination number of $Ni = 4$
$EAN = 28 - 0 + 2 	imes 4 = 36$

What is the $EAN$ of nickel in $Ni(CO)_4$?
