What is the product of the reaction between benzaldehyde and phenylmagnesium bromide?

What is the product of the reaction between benzaldehyde and phenylmagnesium bromide?

Step 1: Identify the reactants. We have benzaldehyde (a type of aromatic aldehyde) and phenylmagnesium bromide (a Grignard reagent).
Step 2: Understand the role of phenylmagnesium bromide. It acts as a nucleophile, meaning it can donate electrons to form new bonds.
Step 3: Recognize that benzaldehyde has a carbonyl group (C=O) that can react with the nucleophile.
Step 4: The phenyl group from phenylmagnesium bromide attacks the carbon atom of the carbonyl group in benzaldehyde.
Step 5: This forms a new carbon-carbon bond and creates an intermediate compound called a benzylic alcohol.
Step 6: The intermediate compound is then protonated (gains a hydrogen ion) to form the final product.
Step 7: The final product of the reaction is Diphenylmethanol, which has two phenyl groups attached to a carbon atom with a hydroxyl (OH) group.
