JEE Advance - Chemistry (2012 - Paper 1 Offline - No. 10)
Which ordering of compounds is according to the decreasing order of the oxidation state of nitrogen?
HNO3, NO, NH4Cl, N2
HNO3, NO, N2, NH4Cl
HNO3, NH4Cl, NO, N2
NO, HNO3, NH4Cl, N2
توضیح
In HNO3, the oxidation state of N is +5 while in NO, it is +2. In N2, it is zero and in NH4Cl, the oxidation state of nitrogen is $$-$$3. So, the decreasing order of oxidation state of nitrogen is
HNO3 > NO > N2 > NH4Cl
