Vedclass · Answer

(C) $1. [Co(NH_3)_5Cl]Cl_2$: In $NH_3$,the oxidation state of $N$ is $-3$. The given value $0$ is for the neutral molecule $NH_3$,not for $N$ itself. However,checking other options for the most incorrect value.$2. NH_2OH$: $x + 3(+1) - 2 = 0 \implies x = -1$. This is correct.$3. (N_2H_5)_2SO_4$: $2(2x + 5) - 2 = 0 \implies 4x + 10 - 2 = 0 \implies 4x = -8 \implies x = -2$. The given value $+2$ is incorrect.$4. Mg_3N_2$: $3(+2) + 2x = 0 \implies 6 + 2x = 0 \implies x = -3$. This is correct.Thus,option $C$ is the incorrectly stated one.
