Question:

Most organic acids can be represented as RCOOH, where COOH is the carboxyl group and R is the rest of the molecule. (For example, R is CH3 in acetic acid, CH3COOH).
(a) Draw a Lewis structure for the carboxyl group.
(b) Upon ionization, the carboxyl group is converted to the carboxylate group, COO2. Draw resonance structures for the carboxylate group.
