Vedclass · Answer

(D) Let us calculate the oxidation state $(X)$ of nitrogen in each compound:$1$. In $[Co(NH_3)_5Cl]Cl_2$,$NH_3$ is a neutral ligand. The oxidation state of $N$ in $NH_3$ is $X + 3(+1) = 0$,so $X = -3$.$2$. In $NH_2OH$,$X + 2(+1) + 1(-2) + 1(+1) = 0$,so $X + 1 = 0$,which means $X = -1$.$3$. In $N_2H_5^+$,$2(X) + 5(+1) = +1$,so $2X = -4$,which means $X = -2$.$4$. In $Mg_3N_2$,$3(+2) + 2(X) = 0$,so $6 + 2X = 0$,which means $X = -3$.Thus,the correct representation is in $Mg_3N_2$ where the oxidation state of $N$ is $-3$.
