The increased viscosity of molten sulfur at 160-195°C is due to the A)melting of S₈ to give discrete S₈ units. B)merging of the S₈ rings to give interlocking S₈ rings. C)opening of the S₈ rings to give smaller S units. D)opening of the S₈ rings which then polymerize into long chains.

Question

Quizplus · Accepted Answer

The increased viscosity of molten sulfur at 160-195°C is due to the opening of the S₈ rings which then polymerize into long chains. This process is known as polymerization and it increases the viscosity of the molten sulfur. Option A and B are not correct because they describe the formation of larger structures in molten sulfur which would decrease the viscosity. Option C is also incorrect because it describes the formation of smaller units which would not explain the increased viscosity.
