Current Question (ID: 8075)

Question:

Molecule/Ion that is diamagnetic in nature is:

Options:

1. $ \text{H}_2^{-} $
2. $ \text{H}_2 $ (Correct)
3. $ \text{H}_2^{+} $
4. $ \text{He}_2^{+} $

Solution:

\text{HINT: } \text{H}_2 \text{ does not have any unpaired electrons.} \n\n \text{Explanation:} \n\n \text{Draw the MOT diagram and find the number of unpaired electrons.} \n\n \text{If it contains an unpaired electron it is paramagnetic and if it does not contains an unpaired electron it is diamagnetic.} \n\n \text{MOT diagrams are :} \n\n 1. \text{H}_2^{-} = \text{Paramagnetic} \n\n (\text{Image of MOT diagram for } \text{H}_2^{-} \text{ is provided in the solution, showing one unpaired electron in } \sigma_{1s}^{\ast} \text{ orbital.}) \n\n 2. \text{H}_2 = 0 \text{ unpaired electron = Diamagnetic} \n\n (\text{Image of MOT diagram for } \text{H}_2 \text{ is provided in the solution, showing both electrons paired in } \sigma_{1s} \text{ orbital.})
