Question

Which of the following is paramagnetic in nature?

• A. $NO$
• B. $N_{2}O$
• C. $N_2{O}_5$
• D. All of the above

Answer 1

The correct option is A $NO$

In $NO$, there is an odd electron which makes it paramagnetic in nature. The total number of electrons is $15$ in the molecule with an odd electron located on either of the atom in two different resonating structures of $NO$.
Hence, (a) is correct.
