MCQ
Which of the following statement is correct
  • A
    $IP$ of $X_{(g)} > E.A$ of $X_{(g)}$
  • B
    $IP$ of $X_{(g)} > IP$ of $X_{(g)}^-$
  • C
    $IP$ of $X_{(g)}^+ > IP$ of $X_{(g)}$
  • ✓
    All are correct
✓

Answer

Correct option: D.
All are correct
d
$IP$ of $X ^{+}( g )\,>\, IP$ of $X ( g )$, Since Zeff of $X ^{+}$is more than $X$ so more energy is needed to extract other $e ^{-}$.

Since $X ^{-}$(negatively charged species has more electron density, hence it can give easily electron so its $IP$ is less than $X$ )

I$\varepsilon$ is greater than $\varepsilon$.A since in $\varepsilon . A$ of neutral species energy generally releases than in I$\varepsilon$ which require more energy to extract an electron.
