# Do all covalent nitrates on heating decompose to give nitrogen dioxide?

Being covalent we can conclude that they will on heating decompose completely, but will they give only $$\ce{NO2}$$ and not any other oxide is the question.

It is observed in $$\ce{Pb(NO3)2, AgNO3,}$$ and also $$\ce{LiNO3}$$ (the anomalous behaviour of $$\ce{Li}$$) that they decompose on heating to give $$\ce{NO2}$$ and the above mentioned nitrates possess good amount of covalent character. So as a rule can I remember that all covalent nitrates decompose to give $$\ce{NO2}$$ or there are any exceptions to it?

• Xenon nitrate has unusual mechanism of decomposition. Apr 23, 2016 at 15:19
• What criteria do you use to state that the lead and silver nitrates possess good amount of covalent character ? Apr 24, 2021 at 11:27
