Question
**Title: Reduction of Benzophenone using NaBH4** **Description:** This page illustrates the reaction mechanism for the reduction of benzophenone using sodium borohydride (NaBH4) and methanol (MeOH). **Reaction Overview:** 1. **Reactant:** - Benzophenone (C6H5)2CO (0.251g) 2. **Reagent:** - Sodium borohydride (NaBH4, 0.138g) 3. **Solvent:** - Methanol (MeOH) 4. **Product:** - Diphenylmethanol (C6H5)2CHOH (0.133g) **Reaction:** - The reduction reaction is represented by the transformation of the carbonyl (C=O) group in benzophenone into a hydroxyl (OH) group, forming diphenylmethanol. **Diagram Explanation:** - **Reactant Side:** The chemical structure of benzophenone, with a central carbonyl group double-bonded to oxygen, is shown. The molecular mass given is 0.251g. - **Arrow Indication:** An arrow points from the reactant structure to the product, indicating the direction of the chemical reaction. - **Reagent and Solvent:** Above the arrow, the reagents NaBH4 (0.138g) and MeOH are indicated, which facilitate the reduction reaction. - **Product Side:** The chemical structure of diphenylmethanol is displayed, showcasing the reduction of the carbonyl group to an alcohol group. The mass of the product is given as 0.133g. **Question:** 2. *Which reactant or product is more soluble in water? Briefly explain why.* **Answer:** - In general, hydroxyl-containing compounds (such as diphenylmethanol) are more soluble in water than carbonyl-containing compounds (such as benzophenone) due to the ability of hydroxyl groups to form hydrogen bonds with water. Therefore, the product, diphenylmethanol, is more soluble in water compared to the reactant, benzophenone. **Conclusion:** The reaction showcases a common organic chemistry reduction, turning a ketone into an alcohol using NaBH4 as the reducing agent in a methanol solvent.
