The major products X and Y formed in the following reaction sequence are
Let's analyze the reaction sequence step-by-step to determine the major products X and Y.
1. **Reaction of Cyclohexanone with Nitroethane (Henry Reaction):**
The first step involves the reaction of cyclohexanone with nitroethane in the presence of ethanol (EtONa and EtOH). This is a classic Henry reaction (or nitro-aldol reaction) that results in the formation of a β-nitro alcohol.
The keto group of cyclohexanone reacts with the anion of nitroethane, leading to the formation of the compound X with a new carbon-carbon bond.
2. **Reduction with TiCl3 and Hydrolysis:**
The second step involves treating compound X with TiCl3 and water. TiCl3 is a reducing agent that can reduce the nitro group to an amino group.
The resultant product Y will have an amino group replacing the nitro group with the retention of the hydroxyl group.
Therefore, the major products in the reaction sequence are aminocyclohexanol derivatives.
Here is the correct product obtained from the reaction:
Thus, the correct answer is represented in the option shown above, which is the reduced product with an amino and hydroxyl group on the ring.
