Question
**Question:** What is the major organic product? **Reaction Details:** The starting material is a cyclic ketone. The reaction involves: 1. Treatment with LiAlH₄ (Lithium Aluminium Hydride) in Et₂O (Diethyl Ether). 2. Followed by addition of H₂O (Water). **Options for the major organic product:** 1. ![Option 1](attached_image) - Structure: A cyclohexane ring with an OH group on the first carbon and another OH group on the third carbon. 2. ![Option 2](attached_image) - Structure: A cyclohexane ring with an OH group on the first carbon and another OH group on the second carbon. 3. ![Option 3](attached_image) - Structure: A cyclohexane ring with an OH group on the first carbon and a double-bonded oxygen (carbonyl) on the third carbon. **Explanation of the Reaction:** Lithium Aluminium Hydride (LiAlH₄) is a strong reducing agent commonly used to reduce carbonyl compounds to alcohols. Here, the cyclic ketone is reduced to a diol (a molecule with two hydroxyl groups). - LiAlH₄ and diethyl ether (Et₂O) is the initial step, wherein the ketone is reduced. The reaction is then quenched with water (H₂O) in the second step to replace the Al-O species with H-O (hydroxyl groups). - The reaction primarily targets the carbonyl group, resulting in a reduction to a secondary alcohol. The correct structure of the major organic product is depicted in the options given. **Identifying the Major Organic Product:** Based on the reduction mechanism described, the product lacking the carbonyl group and showing two hydroxyl (OH) groups will be more favorable. **Select Your Answer:** Choose the correct structural formula for the major organic product below: 1. ![Option 1](attached_image) 2. ![Option 2](attached_image) 3. ![Option 3](attached_image) (This transcription and solution aim to clarify and analyze the given chemical reaction and potential synthetic outcomes for educational purposes.)
