Most organic acids can be represented as RCOOH, in which COOH is the carboxyl group and R is the rest of the molecule. (For exam
ple, R is CH3 in acetic acid, CH3COOH.) (a) Draw the Lewis structure of acetic acid. draw structure ... (b) Upon ionization, the carboxyl group is converted to the carboxylate group, COO−. Draw the Lewis structure for one of the two resonance structures of the acetate anion. (The acetate anion is the ionized form of acetic acid). draw structure ...
Lewis structures, which is also called electron-dot structures or electron-dot diagrams, are diagrams that show the bonding between atoms of a molecule, and the lone pairs of electrons that may exist in the molecule. A Lewis structure can be drawn for any covalently-bonded molecule, as well as coordination compounds.
Draw eight circles and nine more in a big circle = this represents your nucleus draw eight electrons (since electrons = protons in neutral elements) outside of it (2 in one ring, then 6 in a second ring)
