The diagram shows an experimental set-up which can be used in several different experiments.
Which processes could be demonstrate by using the above apparatus?
1. Oxidation of ethanol (liquid X)
2. Dehydration of ethanol (liquid X)
3. Cracking of paraffin (liquid X)
The answer is 2 and 3. I understand that for 2, ethene is produced which is a gas and for 3, cracking of paraffin will produce short-chained hydrocarbons which have low boiling points.
However, I expected 1 to be an answer as well because oxidation of ethanol will produce ethanal which has a boiling point of 21 °C. So shouldn't 1 be an answer as well?
