* Chlorophyll is a complex molecule: It's not a single, pure compound but a mixture of several related pigments. Each of these pigments would have its own decomposition point.
* Decomposition, not boiling: When heated, chlorophyll doesn't boil like water. Instead, it breaks down (decomposes) before reaching a specific boiling point. This decomposition happens at a range of temperatures, depending on the specific chlorophyll pigment and the conditions.
* Factors affecting decomposition: Factors like pressure, exposure to air, and the presence of other molecules influence the temperature at which chlorophyll degrades.
In summary: You can't pinpoint a single "boiling point" for chlorophyll because it decomposes rather than boils.
