The oxidation state of nitrogen is correctly given for

Options

A. Compound = `[CO(NH_(3))_(5)Cl]Cl_(2)`, Oxidation state = `0`
B. Compound = `NH_(2)OH` , Oxidation state = `-2`
C. Compound =`(N_(2)H_(5))_(2)SO_(4)` , Oxidation state = `+2`
D. Compound = `Mg_(3)N_(2)` , Oxidation state = `-3`

Answer

D

Explanation

a. `[Co^(3+)(Noverset(0)H_(3))_(5)Cl^(1-)]^(+2)Cl_(2)^(-1xx2)`
`NH_(3), x+3=0impliesx= -3` Oxidation state of `N = -3`
b. `NH_(2)OH:x+3-2=0impliesx= -1`
Oxidation state of `N= -1`
c. `(N_(2)H_(5))_(2)^(+1xx2)SO_(4)^(2-)`:
`N_(2)H_(5)^(o+): 2x+5= +1implies x= -2`
d. `overset(+2xx3-3xx2)(Mg_(3)N_(2)): "Oxidation state of" N =-3`
