Answer

To determine the final product of the reaction between C₆H₅MgBr (phenylmagnesium bromide) and CO₂ (carbon dioxide) followed by acidification, we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Reactants**: The reactants are phenylmagnesium bromide (C₆H₅MgBr) and carbon dioxide (CO₂).

2. **Understand the Role of C₆H₅MgBr**: C₆H₅MgBr is a Grignard reagent. Grignard reagents act as nucleophiles due to the presence of the negatively charged carbon atom (C) bonded to magnesium (Mg).

3. **Nucleophilic Attack**: The carbon atom in CO₂ has a partial positive charge due to the electronegativity of oxygen. The nucleophilic carbon from C₆H₅MgBr will attack the electrophilic carbon of CO₂. The reaction can be represented as:
\[ C₆H₅MgBr + CO₂ \rightarrow C₆H₅C(=O)O^{-}MgBr^{+} \]
Here, the carbon from the Grignard reagent forms a bond with the carbon of CO₂, resulting in a carboxylate intermediate.

4. **Protonation Step**: The next step involves the addition of an acid (H⁺) to the reaction mixture. This step will protonate the carboxylate ion formed in the previous step, leading to the formation of a carboxylic acid:
\[ C₆H₅C(=O)O^{-} + H^{+} \rightarrow C₆H₅C(=O)OH \]

5. **Final Product**: The final product of the reaction is benzoic acid (C₆H₅COOH).

### Final Answer:
The final product is **benzoic acid (C₆H₅COOH)**.
