MCQ
If a molecule ${X_2}$ has a triple bond, then $X$ will have the electronic configuration
  • A
    $1{s^2}\,\,2{s^2}\,2{p^5}$
  • ✓
    $1{s^2}\,\,2{s^2}\,2{p^3}$
  • C
    $1{s^2}\,2{s^1}$
  • D
    $1{s^2}\,2{s^2}\,2{p^1}$
✓

Answer

Correct option: B.
$1{s^2}\,\,2{s^2}\,2{p^3}$
(b) Molecule $X$ is nitrogen because nitrogen molecule has triple bond. It’s configuration will be $1{s^2},\,\,2{s^2}2{p^3}$.
