Which ordering of compound is according to the decreasing order of th e 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)`

Text Solution

Verified by Experts

The correct Answer is:
B
Let the oxidation state of `N` is `a`.
`{:(HNO_(3)rArr+1+a+3(-2)=0,,:. a= +5,,),(NOrArra+1(-2)=0,,:. a=+2,,),(NH_(4)ClrArra+4(+1)+(-1)=0,,:. a=-3,,),(N_(2)rArr2a=0,,:. a=0,,):}`
Decreasing order of the oxidation state of `N` is
`{:(HNO_(3)",",NO",",N_(2)",",NH_(4)Cl,),(+5,+2,0,-3,):}`
