What is the IUPAC name of CH3CH2CH2OH?
Correct Answer: butan-1-ol
- Step 1: Identify the longest carbon chain in the compound CH3CH2CH2OH. Count the number of carbon atoms in the chain.
- Step 2: The longest chain has 4 carbon atoms, so we start with the base name 'butane'.
- Step 3: Identify the functional group in the compound. The 'OH' group is a hydroxyl group, which indicates that this is an alcohol.
- Step 4: Since the hydroxyl group is attached to the first carbon in the chain, we add '1-' to the name.
- Step 5: Combine the base name and the position of the hydroxyl group to get the full IUPAC name: butan-1-ol.
