Current Question (ID: 7966)

Question:

$\text{The set of oxides of nitrogen that are paramagnetic in nature is:}$

Options:

1. $\text{NO}, \text{N}_2\text{O}$
2. $\text{N}_2\text{O}_3, \text{NO}$
3. $\text{NO}, \text{NO}_2$ (Correct)
4. $\text{N}_2\text{O}, \text{NO}_2$

Solution:

$\text{HINT: Presence of odd electron make molecule paramagnetic.}$ $\text{Explanation:}$ | S.No. | Oxide | Total number of electrons | |---|---|---| | 1 | $\text{NO}$ | 15 | | 2 | $\text{N}_2\text{O}$ | 22 | | 3 | $\text{NO}_2$ | 23 | | 4 | $\text{N}_2\text{O}_3$ | 38 | $\text{NO, and } \text{NO}_2 \text{ are paramagnetic in nature due to the presence of an odd number of electrons.}$
