Question

One mole of $${N}_{2}{H}_{4}$$ loses $$10$$ moles of electrons to form a new compound $$A$$. Assuming that all the nitrogen appears in the new compound, what is the oxidation state of nitrogen in $$A$$? 
[There is no change in the oxidation state of hydrogen]


A
+1

B
3

C
+3

D
+5

Solution

The correct option is C $$+3$$
The oxidation state of N in hydrazine is -2. 
1 mole of hydrazine contains 2 moles of N and loses 10 moles of electrons. Hence, 1 N atom will lose 5 electrons. Hence, its oxidation number will increase by 5. 
Hence, the oxidation number of N in compound A will be $$-2+5=+3$$.

Hence, the correct option is $$C$$
