1a. Circle the stronger acid, and briefly explain why it is a stronger acid, (using arguments based on relative charge stability). Draw one free energy vs. reaction coordinate diagram for each pair of acids that is consistent with your answer.
b. Which of the protons indicated by an arrow is more acidic? Explain why in words and with pictures/other structures, if appropriate (using arguments based on relative charge stability). You do not need to draw a free energy versus reaction coordinate diagram.
