Which functional group is present in the compound CH₃CH₂OH?
Answer
Hydroxyl group (-OH)
The correct answer is Hydroxyl group (-OH) — Therefore the compound contains a hydroxyl group.
Step-by-step solution
- Identify the atoms attached to the carbon chain: the compound has a –OH group attached to the second carbon.
- A functional group containing an oxygen atom attached to hydrogen is the hydroxyl group.
- Therefore the compound contains a hydroxyl group.
Common mistake: Confusing the –OH group with a carboxyl group (-COOH)
