**Reaction Mechanism and Product Prediction**1. **Instruction:** - Show the detailed, step-by-step mechanism using the curvy arrow formalism. - Predict the structure of the product from the following reaction.2. **Reaction Overview:** - **Reactant:** A ketone with a side-chain (molecule on the left with a carbonyl group connected to an ethyl chain). - **Reagents:** 1. Grignard Reagent: R-MgBr in diethyl ether (Et₂O). 2. Acid Workup: H₃O⁺.3. **Mechanistic Steps:** - **Step 1:** The Grignard reagent (R-MgBr) reacts with the carbonyl carbon of the ketone, resulting in nucleophilic addition. The magnesium bromide (MgBr) helps stabilize the negative charge developed on the oxygen. - **Step 2:** Protonation of the alkoxide intermediate occurs via the acidic workup (H₃O⁺), leading to the formation of an alcohol group.4. **Product Structure:** - The resulting product is an alcohol with a newly introduced carbon chain (R group from the Grignard reagent).**Diagram Explanation:**- The diagram shows the skeletal structure of the ketone and the path of the reaction: attacking the carbonyl carbon, followed by the protonation step. Curved arrows indicate electron movement, showing the conversion of the ketone to an alcohol.

An arrow always depicts from a region of high electron density to low electron density ; that is…
