Question

what is the valency of N in NO, N2O AND NO2

Answer 1

In NO-
We know that valency of oxygen (O)is 2
let valency of N be x
so, x-2=0
x=2

similarly
In N2O

2x-2=0
x=2/2
x=1

In NO2
x-2×2=0
x-4=0
x=4



hoping it may help u

Answer 2

Explanation:

We know the valency of oxygen is (-2).

Let the valency of nitrogen is X.

In NO :

X +{ 1× (-2)} = 0

X=+2

In NO2 :

X+{2×(-2)}=0

X=+4

In N2O:

(2×X)+{ 1×(-2)}=0

Hence X=+1

Therefore, Oxidation state of nitrogen in NO is +2 ,in NO2 is +4 and in N2O is +1 .
