One mole of N(2)H(4) loses ten moles of ...

One mole of `N_(2)H_(4)` loses ten moles of electrons of form a new compound Y. Assuming that all the nitrogen appears in the new compound, what is the oxidation state of nitrogen in Y ? (There is no change in the oxidation state of hydrogen.)

A

`-1`

B

`-3`

C

`+3`

D

`+5`

Text Solution

Verified by Experts

The correct Answer is:
C
Total O.N of 2 nitrigen atoms in `N_(2)H_(4)` is -2 since it loses 10 moles of electrons, thereforem the total O.N of two nitrogen atoms in Y increases by 10 i.e., the total O.N of the two introgen atoms in`Y = -4 + 10 = +6`
`:.` O.N of each nitrogen in `Y = 6//2 = +3`.
