One mole of \(\mathrm{N}_2 \mathrm{H}_4\) loses 10 moles of electrons to form a new compound \(Z\). Assuming that all the nitrogens appear in the new compound, what is the oxidation state of nitrogen in \(Z\) ? (There is no change in the oxidation state of hydrogen.)
- A \(-1\)
- B \(-3\)
- C \(+3\)
- D \(+5\)
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 \(\mathrm{N}_2 \mathrm{H}_4\), \(\begin{aligned} \Rightarrow \quad 2 x+4 & =0 \\ 2 x & =-4\end{aligned}\)…
