In which of the following process highest energy is absorbed
  • ✓
    $I \to {I^ - }$
  • B
    $Br \to B{r^ - }$
  • C
    $Cu \to C{u^ + }$
  • D
    $Li \to L{i^ + }$
✓

Answer

Correct option: A.
$I \to {I^ - }$
a
(a) In $Cu$ it has completely filled $d$-orbital so highest energy is absorbed when it convert in $C{u^ + }$ ion.
