Which of the following molecules is not paramagnetic in nature?
- A \(\mathrm{O}_2\)
- B \(\mathrm{O}_2^{+}\)
- C \(\mathrm{O}_2^{-}\)
- D \(\mathrm{O}_2^{2-}\)
Answer & Solution
Correct Answer
(D) \(\mathrm{O}_2^{2-}\)
Step-by-step Solution
Detailed explanation
If all the electrons are paired, the molecule is diamagnetic, while if one or more electron in a molecule is unpaired, the species is paramagnetic. \(\mathrm{O}_2^{2-}\) is not paramagnetic because in \(\mathrm{O}_2^{2-}\) all the electrons are paired, i.e. Configuration of…
