Periodic Table — Medium JEE chemistry MCQ
**[JEE Mains 2026]** What is the correct order of electron gain enthalpy (considering magnitude only) for Group 16 elements?
- A. O > S > Se > Te
- B. S > Se > O > Te
- C. S > O > Se > Te
- D. Se > S > O > Te
Solution
Electron gain enthalpy generally becomes less negative going down the group.
However, oxygen has lower electron gain enthalpy than sulfur due to its small size and electron-electron repulsion.
Order (magnitude): S > O > Se > Te.
