Answer & Solution

Correct Answer

(C) \(+3\)

Step-by-step Solution

Detailed explanation

\(\mathrm{N}_2 \mathrm{H}_4-10 e^{-} \longrightarrow X^{10+}\) (with two \(\mathrm{N}\) atoms) Total oxidation number of two \(\mathrm{N}\) atoms in \(\mathrm{N}_2 \mathrm{H}_4\), \(\begin{aligned} \Rightarrow \quad 2 x+4 & =0 \\ 2 x & =-4\end{aligned}\)…
