The answer is not there, No2^- IS DSAME THING AS NO2^-1

X+2{-2}=-1

X-4=-1

X=4-1

X=3



No2^- dioxonitrate{iii} ion

NO2-
We are looking for the oxidation number of N. This is an ion having a charge of -1 hence, gaining an electron so it will have 1 electron added to the normal NO2.
X+(-2*2)=-1
x+(-4) = -1
x = -1 + 4
x = 3
IUPAC name is : dioxonitrate(III) compound... Or
dioxonitrate(II) ion.

Y is no one considering nitrite here
I was thought dat (NO2^-)is a radical and is called dioxonitrite(iii) ion while (NO3^-)is also a radical and is called trioxonitrate(v) ion .
Radicals are group of atoms with group charge.
Pls someone should consider what I said

d answer is wrong /n+(-2*2)=-1//n-4=-1 /then /n=-1+4 / /n=+3 / so d right answer is dinitrogen(III)oxide

jamb is very tricky
watch the ion NO2- we all forgot the negative sign. in naming ions d second element gives d number.
Nitrogen= -3
Oxygen= x
-3-x=-1.....(_1 is from the negative sign on the NO2-)
-3+1=x
x=2.
Naming from the back
NO2-= di(because of the 2 in oxygen) oxo nitrate 2(d one we got as x)
so d is d answer...dioxonirate2ion

No is nitrogen(¡¡)oxide just like co is carbon(¡¡)oxide therefor i think it is nitrogen(¡¡) ion but is not even in the option

d x correct because d ion x 2 bt d oxidation is 4

The selected answer is wrong:

it can't be dioxonitrate(ii), if it is it will be written as NO...e.g carbon(ii) oxide CO
