**Exercise Instructions:** 1. **Objective**: Draw the tautomer of the given aldehyde. Make sure to include all lone pairs in your drawing. You should ignore inorganic byproducts in this process. 2. **Chemical Structure Provided**: - The chemical structure showcases an aldehyde with a benzene ring (phenyl group) attached to a propanal group (three-carbon chain ending with an aldehyde functional group). 3. **Reaction Condition**: - The conversion is to be performed in the presence of H₃O⁺ (hydronium ion), which acts as a catalyst for the tautomerization reaction. 4. **Response to Input**: - The initial attempt has been marked incorrect, with a reminder that 2 attempts remain. 5. **Diagram Details**: - **Initial Structure**: The image depicts the aldehyde with lone pairs on the oxygen atom. - **Attempted Tautomer Structure**: The drawing reflects an incorrect enol form, where an -OH group is attached to a carbon that was originally near the double-bonded oxygen. 6. **Instruction Visuals**: - The visual representation includes a large arrow indicating the transformation process from the aldehyde to the enol form. - An error indication is shown in the form of a red cross suggesting the attempted tautomer formation is incorrect. **Guidance for Attempts**: - Reevaluate the placement of hydrogen and hydroxyl groups. - Ensure the enol form respects the proper keto-enol tautomerization mechanism, focusing on the proton shift and formation of a new double bond adjacent to the hydroxyl group.
