Correct. The first step (nucleophilic attack), requires two curved arrows, which show the phenol functioning as a
nucleophile and attacking the electrophilic carbonyl group.
Add curved arrow(s) to draw the first step of the mechanism. Modify the given drawings of the product as needed to show the
intermediate that is formed in this step. Use the +/-tools to add/remove charges, and use the single bond tool to interconvert
between double and single bonds.

X Incorrect. Which of the four mechanistic steps is shown in this step of the mechanism?
Add two curved arrow(s) to show step 2: collapse of a charged tetrahedral intermediate. Modify the given drawing of the product
as needed to show the intermediate that is formed in this step. Use the +/- tools to add/remove charges, and use the single bond
