First, draw your chosen compounds including any non-bonding electrons and non-zero formal charges Circle and name any pH-sensitive functional groups. Choose an organic solvent that will dissolve both or your compounds and an aqueous solution (i.e. conc. aqueous NaOH, 5% aq. NaHCO3, or 3M HCl) that would successfully separate the two compounds selected.

In an attempt to synthesize compound C through a two-step process, a chemist discovered after completing the first step that they had inadvertently produced two distinct compounds, A and B. Upon examining the infrared spectroscopy (IR) results, it was observed that both A and B exhibited peaks indicative of a ketone and an ester group. Please provide the molecular structures of A and B. OEt NaOEt ΕΙΟ A B In a chemical experiment, they noticed that both components, A and B, from a combined sample turned into a new compound, C, during the following stage. The task is to determine what compound C looks like and explain how compound A or B changes into compound C through a reaction. Compound C should be the primary molecule containing carbon created in this process, not just a by-product. A B H3O+, H₂O, A Mechanism = с
