Which ordering of compounds is according to the decreasing order of ox

1.	Which ordering of compounds is according to the decreasing order of oxidation state of nitrogen ?
Answer» `HNO_(3),NO,NH_(4)CI,N_(2)` `HNO_(3),NO,N_(2),NH_(4)CI` `HNO_(3),NH_(4)CI,NO,N_(2)` `NO,HNO_(3),NH_(4)CI,N_(2)` SOLUTION :LET the oxidation STATE of nitrogen=x `HNO_(3):(+1)+X+2(-3),x=+5` `NO:x+(-2),x=+2` `Nh_(4)CI: X+4(+1)+(-1),X=-3` `N_(2):2x=0,x=0` Correct decreasing order of oxidation states `underset(+5)HNO_(3) underset(+2)Nounderset(0)N_(2)underset(-3)NH_(4)CI`
