Current Question (ID: 20981)

Question:

$\text{Which of the following species has an odd number of electrons?}$

Options:

1. $\text{NO}_2$
2. $\text{N}_2\text{O}$
3. $\text{N}_2\text{O}_3$
4. $\text{N}_2\text{O}_5$

Solution:

$\text{Hint: If a molecule contains an odd number of electrons then it is called odd e}^- \text{ species}$ $\text{The number of electrons in the given compounds is as follows:}$ $\begin{array}{|c|c|} \hline \text{Species} & \text{Total e}^- \\ \hline \text{NO}_2 & 23 \\ \text{N}_2\text{O} & 22 \\ \text{N}_2\text{O}_3 & 38 \\ \text{N}_2\text{O}_5 & 54 \\ \hline \end{array}$ $\text{The NO}_2 \text{ has an odd number of electrons hence, it is an odd e}^- \text{ species.}$
