Vedclass · Answer

(D) The formula for $EAN$ is $EAN = Z - X + Y$,where $Z$ is the atomic number,$X$ is the oxidation state,and $Y$ is the number of electrons donated by ligands.For $[Co(NH_3)_6]Cl_3$:$1$. The oxidation state of $Co$ $(X)$ is $+3$.$2$. The atomic number of $Co$ $(Z)$ is $27$.$3$. The number of electrons donated by $6$ $NH_3$ ligands $(Y)$ is $6 	imes 2 = 12$.$EAN = 27 - 3 + 12 = 36$.
