Thermal decomposition of lithium nitrate gives:
Thermal decomposition of lithium nitrate gives:
Show Hint
Thermal decomposition of lithium nitrate produces \( NO_2 \), unlike heavier alkali metal nitrates which form nitrites.

The Correct Option is D
Solution and Explanation
Step 1: Thermal Decomposition of Lithium Nitrate
The decomposition reaction for lithium nitrate is: \[ 4LiNO_3 \rightarrow 2Li_2O + 4NO_2 + O_2 \] Step 2: Explanation of Products
Lithium nitrate decomposes to form lithium oxide (\( Li_2O \)), nitrogen dioxide (\( NO_2 \)), and oxygen (\( O_2 \)).
The presence of \( NO_2 \) and \( O_2 \) confirms the decomposition follows a distinct pathway compared to other nitrates.
Thus, the correct answer is (D).
