Question

Using curved arrows to show electron movement, show the mechanisms for each of the reactions below.
Include all formal charges, and do not use any reagents other than those given. 

This image illustrates a chemical reaction involving a rearrangement process. **Reactant:** - The structure on the left is a ketone with an aromatic ring. It features an alkyl group with a hydroxyl group (OH) attached to a carbon atom adjacent to the carbonyl group (C=O). **Reaction Condition:** - The reaction proceeds with the presence of an acidic catalyst, denoted by \( \text{H}^+ \), suggesting an acid-catalyzed reaction. **Product:** - The structure on the right is a lactone, a cyclic ester derived from the reactant. This formation involves a ring closure, where the hydroxyl group has transformed into part of the ester linkage. The reaction showcases the conversion of a hydroxyl group to an ester via a rearrangement, catalyzed by the acid. This type of transformation is common in organic synthesis, particularly in the formation of cyclic compounds.
