Detailed Solution

The given statement is true.
Concept: Sublimation is the direct transition of a substance from the solid to the gaseous state without first going through the liquid state. Recall the process that ammonium chloride goes through and identify the product's phase.
Sublimation is an endothermic process because it takes place at pressures and temperatures below a substance's triple point in its phase diagram.
Ammonium chloride is a white inorganic compound in the solid state with the chemical formula. On heating N H 4 Cl decomposes and forms ammonia and HCl is in the gaseous state. This may seem like sublimation to the eyes. But it is actually not. The reaction involved is as follows;
N H 4 ClN H 3 +HCl
Thus, N H 4 Cl does not undergo sublimation upon heating. So, the given statement is true.
Hence, the correct answer is option 1.
