4. The following compound is a carboxylic acid that contains a bromine atom: C4H7O2Br. The peak at 10.97 ppm was moved onto the chart (which runs only from 0-8 ppm) for clarity. What is the structure of the compound? 5. The following compounds are isomeric esters derived from acetic acid, each with formula C5H10O2. Draw the structures of the two esters?
