How many of the following species are diamagnetic? \[ \mathrm{He}_2^{+}, \mathrm{H}_2, \mathrm{H}_2^{+}, \mathrm{H}_2^{-}, \mathrm{He} \]
- A 1
- B 2
- C 3
- D 0
Answer & Solution
Correct Answer
(B) 2
Step-by-step Solution
Detailed explanation
According to molecular orbital theory, species with all paired electrons in their electronic configuration are diamagnetic in nature. \(\mathrm{He}_2^{+} \rightarrow\) Has total 3 electrons, thus it contains one unpaired electron and is paramagnetic in nature.…
