The paramagnetic nature of oxygen can be explained by

When the reaction $O_2 + e^- \to O_2^-$ occurs,identify the molecular orbital into which the electron is added.

Provide the $MO$ diagram and explain why the $Ne_{2}$ molecule does not exist.

The lowest $O-O$ bond length in the following molecules is:

Which of the following is paramagnetic and contains a three-electron bond in its structure?

Given below are two statements:
Statement $I$: $A$ $\pi$ bonding $MO$ has lower electron density above and below the inter-nuclear axis.
Statement $II$: The $\pi^*$ antibonding $MO$ has a node between the nuclei.
In the light of the above statements,choose the most appropriate answer from the options given below:
