1.	A 2.5 mol of hydrazine `N_(2)H_(4)` loses 25 mole of electrons is being converted to a new compound X. Assuming that all of the nitrogen appears in the new compound, what is the oxidation state of nitrogen in compound X ?A. `-1`B. `-2`C. `+3`D. `+4`
Answer» Correct Answer - C Let the O.N of N in new compound X be be x `overset(+6)(N_(2))H_(4)rarr overset(+x)(2N)+n e^(-)` Let the no. of electron lost per mole of = n `:. 2(-2) = 2x + n (-1)` or `n = 2x + 4 = 2 (x+2)` `:.` No. of electron lost per mole `= 2(x+2)` no. of electrons lost by 2.5 mols `= 2.5 xx 2(2+x)` Now, `2.5 xx 2(2+x) = 25` `5(2+x) = 25` or `2 + x = 5 or x = +3`
