Select the correct Lewis structure for NOCl, a reactive material used as an ionizing solvent.
E)None of these choices are correct.

Question

Quizplus · Accepted Answer

The Lewis structure of NOCl has one nitrogen atom, one chlorine atom, and one oxygen atom. Nitrogen has five valence electrons, chlorine has seven valence electrons, and oxygen has six valence electrons. Therefore, the total number of valence electrons in NOCl is (5+7+6)=18.
To form the Lewis structure, we first connect the atoms by single bonds:
N - O - Cl
There are now 16 electrons left, which we distribute around the atoms as lone pairs and double bonds to satisfy the octet rule:
N=O
|
Cl
The Lewis structure of NOCl has two double bonds (between N and O, and between N and Cl) and one lone pair on nitrogen. This structure best satisfies the octet rule and minimizes formal charges on the atoms.
