Question:
The correct order of electron gain enthalpy is
Correct Option: 1
Solution:
correct order of electron gain enthalpy is :-
$\mathrm{O}<\mathrm{S}>\mathrm{Se}>\mathrm{Te}$
$\Rightarrow \mathrm{S}>\mathrm{Se}>\mathrm{Te}>\mathrm{O}$
(Oxygen shows least electron gain enthalpy due to small size of atom)
