Match items of List-I with those of List-II :
| List - I (Property) |
List - II (Example) |
||
|---|---|---|---|
| (a) | Diamagnetism | (i) | MnO |
| (b) | Ferrimagnetism | (ii) | ${O_2}$ |
| (c) | Paramagnetism | (iii) | NaCl |
| (d) | Antiferromagnetism | (iv) | $F{e_3}{O_4}$ |
Choose the most appropriate answer from the options given below :
Solution
<p> A. NaCl is diamagnetic because all electrons are paired in Na<sup>+</sup> and in Cl<sup>−</sup> . So, it shows diamagnetism. </p>
<p> B. Fe<sub>3</sub>O<sub>4</sub> is ferrimagnetic because of the presence of the unequal alignment of magnetic moment in opposite direction. </p>
<p> C. O<sub>2</sub> molecule has two unpaired electrons. So, it is paramagnetic. </p>
<p> D. In MnO, the orientation of the electrons of Mn and O is such that they cancel their effects, hence it is antiferromagnetic.</p>
