Q. For electron gain enthalpies of the elements denoted as $\Delta_{eg}\mathrm{H}$, the incorrect option is :
A) $\Delta_{eg}\mathrm{H}(\mathrm{Cl}) < \Delta_{eg}\mathrm{H}(\mathrm{F})$
B) $\Delta_{eg}\mathrm{H}(\mathrm{Se}) < \Delta_{eg}\mathrm{H}(\mathrm{S})$
C) $\Delta_{eg}\mathrm{H}(\mathrm{I}) < \Delta_{eg}\mathrm{H}(\mathrm{At})$
D) $\Delta_{eg}\mathrm{H}(\mathrm{Te}) < \Delta_{eg}\mathrm{H}(\mathrm{Po})$
Explanation
The correct answer is Option B: $\Delta_{eg}\mathrm{H}(\mathrm{Se}) < \Delta_{eg}\mathrm{H}(\mathrm{S})$.
