Question

Paramagnetism is exhibited by the molecules which:

• A. are not attracted by magnetic field
• B. contains only paired electrons
• C. carries a positive charge
• D. contains unpaired electrons

Answer 1

The correct option is D contains unpaired electrons

Paramagnetism is when certain materials are weakly attracted by the externally applied magnetic field.
Magnetic moment = $\sqrt{n(n+2)}$ B.M
where n - number of unpaired electrons
Thus, paramagnetism is exhibited by the molecules which have unpaired electrons
