Question

Draw the Lewis structure for each of the following and then determine if the molecule is polar or nonpolar. Do not draw double bonds to oxygen atoms unless they are needed for the central atom to obey the octet rule. Do not include formal charges in your drawing. NO2Cl.

Answer 1

NO2Cl is a polar molecule because the electronegativity difference between atoms of the molecule, being the chloride tho most electronegative. This fact and the asymmetry of the molecule makes a dipole moment.

In order to don’t include formal charges in the drawing you can use the image number 1. Nevertheless is more usual to use a lewis structure like image number 2.
