Propose an efficient synthesis for two of the following target molecules, starting with any of the following starting materials for the source of carbon atoms: (1) benzene, (i) any alcohol containing four or fewer carbon atoms, (1) carbon dioxide, (iv) cyanide ion. This means that any carbon atom that ends up in the target molecule must come from one of these starting materials! Br (a) H2N (b) HO

Many multi-step organic reaction mechanisms involve proton transfer steps. For example, the first step of Fischer esterification of carboxylic acids(as shown with acedic acid) is activation of the acid by protonation. Based on your understanding of which reaction pathway is more favorable, explain why using chemical structures.
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.

The acid-catalyzed hydrolysis of an ester converts an ester into a carboxylic acid. Although there are two O atoms that can be protonated, the first step in the mechanism is believed to be protonation of the oxygen in the C=0 group.
