(a) Sulphur melts form a clear mobile liquid at `119^@ C` but on furth – InterviewSolution

InterviewSolution

1.	(a) Sulphur melts form a clear mobile liquid at `119^@ C` but on further heating to `180^@ C`, it becomes viscous. Why ? (b) `SOCl_2` can act as a weak Lewis acid as well as a weak Lewis base. Explain.
Answer» Sulphur consists of octa-atomic cyclic purkered molecules, At itsmelting point, it becomes a clear liquid, and the rings slip over each other easily. On further heating to a higher temperature, the rings break and long chains are formed. Their network gives rise to a viscous substance.
