Which of the following molecules(s) show/s paramagnetic behavior?
(A) $\mathrm{O}_2$
(B) $\mathrm{N}_2$
(C) $\mathrm{F}_2$
(D) $\mathrm{S}_2$
(E) $\mathrm{Cl}_2$
Choose the correct answer from the options given below :
  1. B only
  2. A & C only
  3. A & E only
  4. A & D only

Solution

$\begin{array}{lcc}
& & \text { No. of unpaired } \mathrm{e}^{-} \\
\text {(A) } & \mathrm{O}_2 & 2 \\
\text { (B) } & \mathrm{N}_2 & 0 \\
\text { (C) } & \mathrm{F}_2 & 0 \\
\text { (D) } & \mathrm{S}_2 & 2 \\
\text { (E) } & \mathrm{Cl}_2 & 0
\end{array}$
If species contain unpaired electron than it is paramagnetic.
So A \& D are paramagnetic.
