Question
**Educational Content: Reaction Product Identification** **Question:** What is the major product of the reaction shown below? **Reaction Details:** 1. Reactants: A linear alkyl lithium reagent (alkyllithium) 2. Reactant: Benzaldehyde (a benzene ring with a formyl group, C=O, attached) 3. Conditions: Acidic water (H⁺/H₂O) The reaction proceeds with the following reagents: 1. Alkyllithium reacts with benzaldehyde. 2. Following the reaction, the mixture is treated with an acidic aqueous solution (H⁺/H₂O). **Product Options:** - **Compound A:** - Structure: A phenyl group (benzene ring) attached to a long alkyl chain with a ketone (C=O) at the end. - **Compound B:** - Structure: A phenyl group linked to a ketone group directly, with an alkyl chain extending further. - **Compound C:** - Structure: A phenyl group attached to a secondary alcohol (OH group), with the alkyl chain branching off the carbon bearing the hydroxyl group. - **Compound D:** - Structure: A phenyl group bonded to an alkyl chain ending in a ketone group (C=O). **Selection Options:** - ○ Compound A - ○ Compound D - ○ Compound B - ○ Compound C **Explanation:** - This reaction typically involves the addition of the organometallic reagent (alkyllithium) to the carbonyl group of benzaldehyde, followed by protonation during aqueous workup to form an alcohol. - Thus, it is important to identify which compound represents an alcohol product resulting from the carbonyl group reacting with the alkyllithium. **Conclusion:** Select the compound that matches the expected product of an alcohol addition reaction from the given options.
