Current Question (ID: 8074)

Question:

A paramagnetic molecule among the following is:

Options:

1. $ \text{O}_2^{-} $ (Correct)
2. $ \text{CN}^{-} $
3. $ \text{NO}^{+} $
4. $ \text{CO} $

Solution:

\text{HINT: Molecule/ions containing unpaired electrons are paramagnetic in nature.} \n\n \text{Explanation:} \n\n \text{The MOT diagram of } \text{O}_2^{-} \text{ is as follows:} \n\n (\text{Image of MOT diagram is missing, but the explanation clarifies.}) \n\n \text{The } \text{O}_2^{-} \text{ has one unpaired electron in its } \pi_{2p_{x}}^{\ast} \text{ molecular orbital. Hence, it is paramagnetic in nature.}
