About this Site | Report a Problem | Comments & Suggestions, Stoichiometry: Moles, Grams, and Chemical Reactions. The key to drawing this structure is realizing this COOH right here is what we call a functional group. Since all the atoms are in either period 1 or 2, this molecule will adhere to the octet rule. I quickly take you through how to draw the Lewis Structure of CH3OH (Methanol or methyl alcohol) . The exception, of course, being the hydrogen's. Table vinegar tends to be more diluted (4% to 8% acetic acid), while commercial food pickling, in general, employs more concentrated solutions. Question = Is CH3COOH polar or nonpolar ?
