###### FREE Expert Solution

We’re being asked to determine the correct order of halo-substituted acetic acids from the least acidic on the left to the most acidic on the right.

Acetic acid has a formula of CH3COOH or CH3CO2H. Let’s draw the Lewis structure of acetic acid using the following steps:

Step 1: Determine the central atom in this molecule.
Step 2: Calculate the total number of valence electrons present.
Step 3: Draw the Lewis structure for the molecule.
