6. Write the complete stepwise mechanism for the reaction below. Show all intermediate structures and show the flow of electrons for each step using curved arrows. pyridineSOCl2 7. The relative reactivities of the carboxylic acid derivatives are roughly inversely related to the conjugate base strength of the tetrahedral intermediate leaving group. Draw acetic acid and the following derivatives of acetic acid in the blank boxes in order of increasing reactivity (leftmost box is least reactive). You must draw acetic acid, an acid bromide, an acid chloride, a primary amide, and an ethyl ester
