The shape of colourless neutral gas formed on thermal decomposition of ammonium nitrate is

The shape of colourless neutral gas formed on thermal decomposition of ammonium nitrate is
  1. Angular
  2. Linear
  3. Trigonal planar
  4. Trigonal pyramidal

Solution

Ammonium nitrate $\left(\mathrm{NH}_4 \mathrm{NO}_3\right)$ on thermal decomposition produces $\mathrm{N}_2 \mathrm{O}$ and $\mathrm{H}_2 \mathrm{O}$ $\mathrm{NH}_4 \mathrm{NO}_3 \longrightarrow \mathrm{~N}_2 \mathrm{O}$ (colourless gas) $+\mathrm{H}_2 \mathrm{O}$ $\mathrm{N}_2 \mathrm{O} \Rightarrow: \mathrm{N} \equiv \mathrm{~N}-\ddot{\mathrm{O}}:$ Linear $\mathrm{N}_2 \mathrm{O}$ is also known as laughing gas.
