Question

Quizplus · Accepted Answer

In N2H4 (hydrazine), the oxidation number of hydrogen is +1. Since there are four hydrogen atoms, their total contribution is +4. The molecule is neutral, so the sum of oxidation numbers must be zero. Therefore, the oxidation number of each nitrogen must be -2 to balance the +4 from hydrogen, resulting in a total of -4 for the two nitrogen atoms.
