Q48. At elevated temperature (~1000 K) the dominant form of sulphur is: (a) Rhombic Sulphur (b) Monoclinic Sulphur (c) S8 molecules (d) S2

At high temperatures (above 1000 K), the S8 rings (present in rhombic and monoclinic sulfur) break down into smaller units. At temperatures around 1000 K and higher, S2 is the dominant form of sulfur vapor. S2 molecules are paramagnetic, similar to O2, due to the presence of two unpaired electrons in their molecular orbitals.

What is the correct answer for CUET UG Chemistry Q48?

The correct answer is d. At high temperatures (above 1000 K), the S8 rings (present in rhombic and monoclinic sulfur) break down into smaller units. At temperatures around 1000 K and higher, S2 is the dominant form of sulfur vapor. S2 molecules are paramagnetic, similar to O2, due to the presence of two unpaired electrons in their molecular orbitals.
