$NO$

Vedclass · Answer

(B) The octet rule states that atoms tend to gain,lose,or share electrons to achieve a stable configuration of $8$ valence electrons. In $CO_2$,$H_2O$,and $O_2$,all atoms (except $H$ in $H_2O$) achieve an octet. In $NO$ (Nitric oxide),the nitrogen atom has $5$ valence electrons and the oxygen atom has $6$ valence electrons,totaling $11$ valence electrons. Since the total number of valence electrons is odd,it is impossible for all atoms to satisfy the octet rule,making $NO$ an odd-electron molecule.

The octet rule is not valid for which of the following molecules?
