Question

Rhombic sulphur Consists of:

• A. S₄ Rings
• B. S₈ Rings
• C. S₈Chains
• D. S₂ Molecules

Answer 1

The correct option is B

S₈ Rings

Explanation of correct option:

Option B

• The stable form of Sulfur that exists at room temperature or can say below 369K is rhombohedral which exists as S₈ rings.
• Rhombic sulfur is a crystalline allotropic form of sulfur
• It is insoluble in water but dissolves to some extent in benzene, alcohol, and ether.
• It is readily soluble in CS₂(Carbon disulfide)_.
• It has little thermal and electrical conductivity.
• It consists of eight Sulfur atoms arranged in an octahedral shape.

Explanation of incorrect option:

Option A

• S₄ rings have more angle strain so unstable at room temperature.

Option C

• S₈ Chains does not exist

Option D

• S₂ molecule does not exist due to low bond enthalpy of the S-S bond.

Hence, option (B) is correct.
