Question

$N{O}_2$ does not obey octet rule because:

• A. It has odd number of electrons
• B. It has extended octet
• C. Nirogen cannot obey octet in its compounds
• D. None of the above

Answer 1

The correct option is A It has odd number of electrons

There are a number of molecules whose total number of valence electrons is an odd number. It is not possible for all of the atoms in such a molecule to satisfy the octet rule. In nitrogen dioxide $\left(N{O}_2\right)$, each oxygen atom contributes six valence electrons and the nitrogen atom contributes five for a total of seventeen. The lewis dot strucutre of $N{O}_2$ is given below:
