Question: The correct order of electron gain enthalpy is:
$\mathrm{S}>\mathrm{Se}>\mathrm{Te}>\mathrm{O}$
$\mathrm{O}>\mathrm{S}>\mathrm{Se}>\mathrm{Te}$
$\mathrm{S}>\mathrm{O}>\mathrm{Se}>\mathrm{Te}$
$\mathrm{Te}>\mathrm{Se}>\mathrm{S}>\mathrm{O}$
Correct Option: 1
Solution:
Electron gain enthalpy of $\mathrm{O}$ is very low due to small size.
