Question
Which conditions are used to convert ethanol to ethanal?A. Excess oxidizing agent and refluxB. Excess oxidizing agent and distillationC. Excess ethanol and refluxD. Excess ethanol and distillation
Solution
The correct condition to convert ethanol to ethanal is B. Excess oxidizing agent and distillation.
Here's the step by step process:
- Ethanol is heated with an excess of the oxidizing agent.
- The oxidizing agent commonly used is acidified potassium dichromate (VI) solution.
- The reaction is carried out under distillation conditions.
- As soon as the ethanal is formed, it is distilled off as a vapor before it gets a chance to further oxidize to ethanoic acid.
- The ethanal is then condensed back into a liquid in a separate container.
