Question

Which among the following is an odd electron molecule?

• A. $\mathrm{NO}$
• B. ${\mathrm{NO}}_2$
• C. ${\mathrm{ClO}}_2$
• D. all of these

Answer 1

The correct option is D

all of these

The explanation for correct option

(D) all of these

Odd electron molecule

• Odd electron molecules are molecules whose total number of valence electrons is an odd number.
• The number of valence electrons in $\mathrm{NO}$ is $5+6=11$.
• The number of valence electrons in ${\mathrm{NO}}_2$ is $5+6\times 2=17$.
• The number of valence electrons in ${\mathrm{ClO}}_2$ is $7+6\times 2=19$.
• So, in all the given molecules, the total number of valence electrons is an odd number.
• So, all the given molecule is odd electron molecule.

.

Hence, option (D) is correct. All the given molecule is Odd electron molecule.
