MCQ
In which of the following process, least energy is required :-
- A$F_{(g)}^- \to F_{(g)} + e^-$
- ✓$P_{(g)}^- \to P_{(g)} + e^-$
- C$S_{(g)}^- \to S_{(g)} + e^-$
- D$Cl_{(g)}^- \to Cl_{(g)} + e^-$
✓
Answer
Correct option: B.
$P_{(g)}^- \to P_{(g)} + e^-$
b
$A_{(g)}^ - \xrightarrow[{I.P.}]{}{A_{(g)}} + {e^ - }$
$A_{(g)}^ - \xrightarrow[{I.P.}]{}{A_{(g)}} + {e^ - }$
$A_{(g)}^ - \xrightarrow[{E.A.}]{}{A_{(g)}} + {e^ - }$
$\mathrm{E.A.}$ of $\mathrm{A}_{(\mathrm{g})}=\mathrm{IP}$ of $\mathrm{A}_{(\mathrm{g})}^{-}$
$EA$ onder
$\mathrm{P}<\mathrm{S}<\mathrm{F}<\mathrm{Cl}$
$IP$ order
$\mathrm{P}^{-}<\mathrm{S}^{-}<\mathrm{F}^{-}<\mathrm{Cl}^{-}$
