Vedclass · Answer

(A) The $EAN$ (Effective Atomic Number) is calculated using the formula: $EAN = Z - 	ext{oxidation state} + 2 	imes 	ext{coordination number}$.For $[Co(NH_3)_6]^{3+}$:$1$. The atomic number $(Z)$ of $Co$ is $27$.$2$. The oxidation state of $Co$ is calculated as $x + 6(0) = +3$,so $x = +3$.$3$. The coordination number is $6$ (since $NH_3$ is a monodentate ligand).$4$. $EAN = 27 - 3 + 2(6) = 24 + 12 = 36$.
