JEE MAIN - Chemistry (2025 - 24th January Morning Shift - No. 2)
The large difference between the melting and boiling points of oxygen and sulphur may be explained on the basis of
Atomicity
Electron gain enthalpy
Atomic size
Electronegativity
Explanation
Oxygen exists as $\mathrm{O}_2$ (Atomicity $=2$)
Sulphur exists as $\mathrm{S}_8($ Atomicity $=8)$
Hence, Melting point & Boiling point of sulphur are significantly large compared to oxygen.
