Question
**Exercise 2: Drawing Keto, Enol, and Enolate Forms** **Instructions:** Carefully draw the keto form of the compound for which the enol is drawn; then draw its enolate form by removing the acidic proton, and show two resonance forms of it. **Diagram Details:** 1. **Keto Form:** - On the left side of the diagram, there is an empty rectangular box labeled "keto form." 2. **Enol Form:** - In the middle, there is a structure displaying the enol form of the compound. - The skeletal structure consists of a double bond between two carbon atoms. - Attached to one of the doubly-bonded carbons, there is an OH group (hydroxyl group). - The diagram shows an 'arrow' pointing from the keto form to the enol form. 3. **Enolate Forms:** - To the right of the enol form, there is an instruction "- H⁺" (indicating the removal of an acidic proton). - Subsequently, there are two empty rectangular boxes placed horizontally side by side with a bi-directional arrow between them, signifying resonance forms. - These boxes are labeled "enolate forms." **Diagram Summary:** - From left to right: **Keto form** → **Enol form** → **Enolate forms (two resonance forms)**. Please use the empty boxes to draw the respective structures as per the instructions. Some guidance on the structures: - **Keto Form:** A carbonyl group (C=O) within the compound. - **Enolate Form:** Resulting from deprotonation of the enol form, showing resonance between two structures: 1. A carbon-hydrogen double bond (C=C) with a negatively charged oxygen (O⁻). 2. A carbon-hydrogen single bond (C-N) with a negative charge on the carbon (C⁻) adjacent to a double-bond carbon-oxygen (C=O).
