How many of the following molecules ions are paramagnetic in nature?
\[
\mathrm{N_2,\ O_2,\ F_2,\ NO,\ CO,\ O_2^-,\ O_2^{2-},\ N_2^+,\ NO^+,\ NO^-,\ H_2}
\]
Show Hint
- \(7\)
- \(6\)
- \(5\)
- \(4\)
The Correct Option is B
Solution and Explanation
Step 1: Identify the paramagnetic species using Molecular Orbital Theory.& nbsp;
The given species are classified as follows:
\[ \begin{aligned} \text{Paramagnetic:}\quad & amp;\mathrm{O_2,\ NO,\ O_2^-,\ N_2^+,\ NO^-},\\[4pt] \text{Diamagnetic:}\quad & amp;\mathrm{N_2,\ F_2,\ CO,\ O_2^{2-},\ NO^+,\ H_2}. \end{aligned} \]
Thus, the number of paramagnetic species is
\[ 5. \]
Step 2: Write the answer.
Hence,
\[ \boxed{5}. \]
Thus, the correct option is
\[ \boxed{(B)}. \]
