WebEAN rule :- The total number of e −s linked with the central metal atom or ion in a complex plus the e −s donated by the ligand is known as Effective Atomic Number, i.e; EAN. It is the attainment of noble gas configuration. EAN=Z−x+2nL Z = atomic number of the metal in the complex ion. x = oxidation state of the central metal atom. WebCorrect option is A) EAN i.e Effective Atomic Number is nothing but the total number of electrons present on each atom in the given compounds. The oxidation state of metal in metal carbonyl's is zero. The structure of Co 2CO 8 is as shown above.
