Question

Sulphur can also exist in an amorphous form – True or False?

• A. True
• B. False

Answer 1

The correct option is A True

When heated to ${113}^{\circ }C$ Orthorhombic sulphur melts and if we continue heating this molten yellow liquid, it darkens above ${160}^{\circ }C$ and becomes more viscous as the Sulphur rings break open and polymerize. The resulting helical $S_n$ polymers can be extracted from the melt by pouring the molten Sulphur in water (called quenching). This super-cooled liquid is a metastable rubber-like material that slowly converts back to stable $\alpha -S_8$ at room temperature. Different polymeric chains can have different number of atoms and isolating a particular strain becomes difficult. Obviously these polymeric forms are amorphous
