Compound	Oxidation
$N{H}_3$	+3
$[Co(N(H{)}_3{)}_{5}Cl]$	+1
$M{g}_3{N}_2$	-3
$N{H}_{2}OH$	+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) $\text{N}{\text{H}}_3$ $\to -3$

(b) $[\text{C}\text{o}(\text{N}{\left(\text{H}\right)}_3{)}_5\text{C}\text{l}]$ $\to -3$

(c) $\text{M}{\text{g}}_3{\text{N}}_2$ $\to -3$

(d) $\text{N}{\text{H}}_2\text{O}\text{H}$ $\to -1$

$\therefore$ Correct answer is option (c)
