Question

Give examples of compounds of N with oxidation number -3 .

• A. $N{H}_3$
• B. $N_2{H}_4$
• C. $NO$
• D. All of the above

Answer 1

The correct option is A $N{H}_3$

A. $N{H}_3$ having N oxidation number is -3

in NH3, H is having +1 charge

so X + 3 = 0 here x is oxidation nomber of nitrogen

so x = -3

B. in $N_2{H}_4$ having -2 oxidation no of N

H have +1 charge

so the 2x+4 = 0 here x is oxidation no of nitrogen

x = -2

C. in $NO$

oxygen have -2 charge

so x +(-2) = 0 here x is oxidation no of nitrogen

x = +2
