A mole of `N_(2)H_(4)` loses 10 mol of electrons to 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 number of hydrogen)

A

`-1`

B

`-3`

C

`+3`

D

`+5`

Text Solution

Verified by Experts

The correct Answer is:
C

Change in `e ^(-) = n - (-2)`
`=n +2`
`So n ( n +2) = 10`
` 2n + 4 = 10`
` 2n = 6`
`n = 3`
