Question

Molecular formula of sulphur at ordinary temperature is:

• A. S\(_2\)
• B. S\(_4\)
• C. S\(_6\)
• D. S\(_8\)

Hint:

Sulphur commonly exists as S\(_8\) molecules at room temperature, forming a crown-shaped cyclic structure.

Answer 1

The Correct Option is D

Step 1: Physical state of sulphur.
At ordinary temperature, sulphur exists in the solid state. Its most stable form is rhombic sulphur.
Step 2: Molecular structure.
In rhombic sulphur, each molecule consists of 8 sulphur atoms forming a puckered ring (crown shape). Hence, its molecular formula is S\(_8\).
Step 3: Conclusion.
Therefore, the correct molecular formula of sulphur at ordinary temperature is (D) S\(_8\).
