MCQ
The process requiring the absorption of energy is
- A$F \to {F^ - }$
- B$Cl \to C{l^ - }$
- ✓$O \to {O^{2 - }}$
- D$H \to {H^ - }$
✓
Answer
Correct option: C.
$O \to {O^{2 - }}$
c
(c) The second $I.E.$ is greater than first $I.E.$ similarly second $E.A.$ is greater than first $E.A.$ the energy is to be supplied to force the second ${e^ - }$ into the anion.
