On heating rhombic sulphur it melts but ...

On heating rhombic sulphur it melts but viscosity of liquid increases upto `200^(circ)C`and beyond that it dercreases why?

Text Solution

Verified by Experts

The correct Answer is:
On heating, `S_(8)` rings are broken and long chain polymers are formed up to `200^(circ)C`. Thus due to polymerisation, liquid becomes viscous but beyond `200^(circ)C` long chains are broken into short chains and ultimately `S_(2)` moleucles are formed in the vapour phase, so viscosity of liquid decreases.
