Q. Consider the following pairs:
| Sulfur Allotrope | Property/Characteristic |
| Rhombic sulfur | Stable at room temperature |
| Monoclinic sulfur | Stable at high temperature |
| Plastic sulfur | Amorphous form obtained by rapid cooling |
| Colloidal sulfur | Used in medicinal suspensions |
How many of the above pairs are correctly matched?
Answer:
All Four Pairs
Notes: Rhombic sulfur is stable at room temperature. Monoclinic sulfur is stable at higher temperatures. Plastic sulfur is an amorphous allotrope obtained by rapid cooling of molten sulfur. Colloidal sulfur is used in medicinal suspensions. All pairs are correctly matched.
