$NH_3$	+3
$[Co(N(H)_{3})_{5}Cl]$	+1
$Mg_{3}N_{2}$	-3
$NH_{2}OH$	+1

• A. A
• B. B
• C. C
• D. D

Answer 1

Answer: (C)

Correct oxidation number, for N-atom is compound oxidation number of N-atom

(a) $\text{N}\text{H}_{3}$ $ \rightarrow -3$

(b) $\left[\right.\text{C}\text{o}\left(\right. \text{N} \left(\text{H}\right)_{3} \left.\right)_{5}\text{C}\text{l}\left]\right.$ $ \rightarrow -3$

(c) $\text{M}\text{g}_{3}\text{N}_{2}$ $ \rightarrow -3$

(d) $\text{N}\text{H}_{2}\text{O}\text{H}$ $ \rightarrow -1$

$\therefore $ Correct answer is option (c)
