Answer 1

Experiment Report: Synthesis of Benzoic Acid and Benzyl Alcohol

Aim/Objective:
The aim of this experiment is to synthesize benzoic acid and benzyl alcohol through the oxidation of benzaldehyde using potassium permanganate as the oxidizing agent.

Chemicals/Apparatus:
- Benzaldehyde
- Potassium permanganate
- Sulfuric acid
- Distilled water
- Ice bath
- Separatory funnel
- Glassware for reflux setup
- Rotary evaporator

Procedure:
1. Prepare a reflux setup with a round-bottom flask containing benzaldehyde, sulfuric acid, and distilled water.
2. Add potassium permanganate in small portions to the reaction mixture while stirring constantly.
3. Place the round-bottom flask in an ice bath to control the temperature.
4. Allow the reaction to proceed for a set amount of time, then cool the mixture to room temperature.
5. Transfer the reaction mixture to a separatory funnel and extract the organic layer.
6. Use a rotary evaporator to remove solvents and isolate the products.

Observation:
- The color of the reaction mixture will change as the potassium permanganate is added.
- Formation of a white precipitate indicates the formation of benzoic acid.
- Benzyl alcohol can be separated as a colorless liquid during extraction.

Results:
- Benzoic acid and benzyl alcohol were successfully synthesized through oxidation of benzaldehyde.

Conclusion:
The experiment successfully demonstrated the synthesis of benzoic acid and benzyl alcohol using potassium permanganate as the oxidizing agent. The products were isolated through extraction and evaporation techniques. This experiment showcases the versatility of oxidation reactions in organic chemistry.

Calculation (if available):
The yield of the products can be calculated by weighing the isolated benzoic acid and benzyl alcohol and comparing it to the theoretical yield based on the starting amount of benzaldehyde used in the reaction.
