Write a short note on the allotropy of sulphur. |
|
Answer» The important allotropes of sulphur are a) yellow rhombic (`alpha`. Sulphur) b) Monoclinic (`beta` - sulphur) `to` The stable from is `alpha`-sulphur (at room temperature) Rhombic sulphur (`alpha`-Sulphur) : `to` Colour : Yellow. `to` Melting point : 385.8K. `to` Specific gravity : 2.06. `to` It is insouble in water and partially soluble in alcohol, benzene etc. and readily soluble in `CS_(2)`. Monoclinic sulphur (`beta` - Sulphur) : `to` Melting point : 392K `to` Specific gravity : 1.98. `to` It is soluble in `CS_(2)`. `to` Rhombic sulphur transforms to monoclinic sulphur by heating above 369K. This temperature is called transition temperature. |
