Advertisements
Solution
| Property | White Phosphorus | Red Phosphorus |
| Appearance and Smell: | It is a soft, waxy solid with a garlic-like smell. | It is a hard, crystalline solid without any smell. |
| Toxicity: | It is poisonous. | It is non-poisonous. |
| Solubility: | Insoluble in water but soluble in carbon disulphide. | Insoluble in both water and carbon disulphide. |
| Reactivity: | Undergoes spontaneous combustion in air. | Comparatively less reactive and stable in air. |
| Structure: | Exists as discrete P4 molecules in both solid and vapour states. | Exists as a polymeric chain of linked P4 tetrahedra. |
