###### FREE Expert Solution

We are asked which of the following molecules is not a polar molecule.

To do so, we first need to draw a Lewis structures

For this, we need to do the following steps:

Step 1: Determine the central atom in the molecule.

Step 2: Calculate the total number of valence electrons present.

Step 3: Draw the Lewis structure for the molecule.

Step 4: Check the dipoles
