Which is the most stable allotrope of sulphur ?

A

Octahedral sulphur

B

Monoclinic sulphur

C

Plastic sulphur

D

Colloidal sulphur

Text Solution

Verified by Experts

The correct Answer is:
A
Octahedral sulphur (rhombic or ` alpha `-sulphur ) is the most stable allotrope of sulphur . It is stable at temperature below `95.6^(@)C` . Its specific gravity is 2.06. It melts at `114^(@)C` . It is soluble in carbon disulphide . Its crystal structure contains cyclic `S_(8)` rings packed in a manner which leads to the formation of rhombic crystals.
