5 In the condensation reaction used in Part B, the water molecule is produced when a -OH from the carboxylic acid functional group in one molecule bonds to the proton of an alcohol functional group in the other molecule. Consider the two molecules below and answer the questions that follow. OH HO H₂SO4 a. Circle the -OH of the carboxylic acid group and the proton of the alcohol that combine to form H₂O. b. Recall that oxygen generally participates in two bonds and carbon participates in four. Draw a dotted line between the two atoms in the organic molecules that must bind to each other in order to maintain the typical bonding numbe for all atoms if the circled elements of the H₂O molecule separate from the reactants. c.
