The oxidation state of nitrogen is correctly given for

Options

A. `{:("Compound","Oxidation state"),([Co(NH_3)_5 Cl]Cl_2,0):}`
B. `{:("Compound","Oxidation state"),(NH_2OH,-2):}`
C. `{:("Compound","Oxidation state"),((N_2H_5)_2 SO_4,+2):}`
D. `{:("Compound","Oxidation state"),(Mg_3N_2,-3):}`

Answer

D

Explanation

A) `[Co^(+3)(NH_3)_5^(0) Cl^(1-)]^(+2) Cl_2^(-1 xx 2), NH_3 , x + 3 = 0 implies x = -3`, oxidation state of N = -3.
B) `NH_2OH , x + 3 - 2 = 0 implies x = -1`, Oxidation state of N = -1
C) `(N_2H_5)^(+1 xx 2) SO_4^(2-) , N_2H_5^(o+) , 2x + 5 = +1 implies x = -2`, Oxidation number of N = -2
D) `overset(+2 xx 3)(Mg_3) overset(-3 xx 2)(N_2)`, Oxidation state of `N = -3`
