Which of the compounds among \(\mathrm{N}_2 \mathrm{O}, \mathrm{NO}\), \(\mathrm{N}_2 \mathrm{O}_3, \mathrm{NO}_2, \mathrm{~N}_2 \mathrm{O}_4, \mathrm{~N}_2 \mathrm{O}_5\) are diamagnetic?
- A \(\mathrm{NO}, \mathrm{NO}_2, \mathrm{~N}_2 \mathrm{O}_3\)
- B \(\mathrm{N}_2 \mathrm{O}, \mathrm{N}_2 \mathrm{O}_3, \mathrm{~N}_2 \mathrm{O}_4, \mathrm{~N}_2 \mathrm{O}_5\)
- C \(\mathrm{NO}, \mathrm{NO}_2\)
- D \(\mathrm{N}_2 \mathrm{O}_4, \mathrm{~N}_2 \mathrm{O}_5\)
Answer & Solution
Correct Answer
(B) \(\mathrm{N}_2 \mathrm{O}, \mathrm{N}_2 \mathrm{O}_3, \mathrm{~N}_2 \mathrm{O}_4, \mathrm{~N}_2 \mathrm{O}_5\)
Step-by-step Solution
Detailed explanation
Let us draw the structure of nitrogen oxides. \(\mathrm{N}_2 \mathrm{O}, \mathrm{N}_2 \mathrm{O}_3, \mathrm{~N}_2 \mathrm{O}_4, \mathrm{~N}_2 \mathrm{O}_5\) do not have unpaired electrons \((n=0)\). So, they are diamagnetic \((\mu=0)\).
