The correct Answer is:
To determine the product formed when phenyl magnesium bromide reacts with t-butanol, we can follow these steps: ### Step 1: Identify the Reactants - The reactants in this case are phenyl magnesium bromide (C6H5MgBr), which is a Grignard reagent, and t-butanol (C4H10O). ### Step 2: Understand the Nature of Grignard Reagents - Grignard reagents are highly reactive organometallic compounds. The phenyl group (C6H5-) in phenyl magnesium bromide carries a negative charge, while the magnesium bromide (MgBr) part carries a positive charge. ### Step 3: Analyze the Reaction with t-Butanol - t-Butanol is a tertiary alcohol, which means it has a hydroxyl (-OH) group attached to a carbon that is bonded to three other carbon atoms. The hydroxyl group in t-butanol can release a proton (H+) due to its acidic nature. ### Step 4: Reaction Mechanism - When phenyl magnesium bromide reacts with t-butanol, the negatively charged phenyl group (C6H5-) will react with the proton (H+) from the hydroxyl group of t-butanol. This results in the formation of benzene (C6H6) and a t-butoxide ion (C4H9O-). ### Step 5: Write the Balanced Equation - The balanced reaction can be represented as: \[ C6H5MgBr + (CH3)3COH \rightarrow C6H6 + (CH3)3CO^- \] - Here, benzene (C6H6) is formed as the main product, and the remaining product is the t-butoxide ion. ### Conclusion - The product formed when phenyl magnesium bromide reacts with t-butanol is **benzene (C6H6)**. ---
