Which of the following compound on heating gives N2O ?
- Pb(NO3)2
- NH4NO3
- NH4NO2
- NaNO3
The Correct Option is B
Solution and Explanation
When ammonium nitrate \((NH_4NO_3)\) is heated, it decomposes to form nitrous oxide \((N_2O)\), water, and nitrogen dioxide:
\(2 NH_4NO_3 → 2 N_2O + 4 H_2O + O_2\)
This reaction is a classic example of the decomposition of ammonium nitrate on heating, producing \(N_2O\) (nitrous oxide), which is also known as laughing gas.
The correct answer is (B) : \(NH_4NO_3\).
