You can't directly derive an aldehyde from ethane (CH₃CH₃). Here's why:

* Aldehydes have a carbonyl group (C=O) directly attached to a hydrogen atom. Ethane lacks a carbonyl group.

* To form an aldehyde, you need to introduce a carbonyl group and a hydrogen atom to the carbon chain. This requires oxidation.

Here's how you would get an aldehyde from a related compound:

1. Start with ethanol (CH₃CH₂OH), which has a hydroxyl group (OH) attached to the carbon chain.

2. Oxidize ethanol: This can be done using oxidizing agents like potassium dichromate (K₂Cr₂O₇) in the presence of acid.

3. The oxidation process removes the hydrogen from the hydroxyl group and forms a carbonyl group. This results in acetaldehyde (CH₃CHO), which is the aldehyde derived from ethane's corresponding alcohol.
