Question

Which ordering of compounds is according to the decreasing order of the oxidation state of nitrogen ?
A. `HNO_(3), NO, NH_(4)Cl, N_(2)`
B. `HNO_(3), NO, N_(2), NH_(4)Cl`
C. `HNO_(3), NH_(4)Cl, NO, N_(2)`
D. `NO, HNO_(3), NH_(4)Cl, N_(2)`

Answer 1

Correct Answer - B
`overset(+1x-2)(HNO_(3)), " " 1+x-6=0, x=+5`
`overset(x-2)(NO, x-2=0,x=+2`
`Na_(2)` , oxidation state of N=0
`overset(x+1-1)(NH_(4)Cl), " " x+4xx1-1=0,x=-3`
The decreasing order of oxidation states is :
`HNO_(3) gt NO gt N_(2) gt NH_(4)Cl`
