Q: What is the IUPAC name for the compound with the structure CH3-CO-CH2-CH3?
Solution: The compound has a ketone functional group on the second carbon of a four-carbon chain, making it butan-2-one.
Steps: 4
Step 1: Identify the longest carbon chain in the structure CH3-CO-CH2-CH3. The longest chain has 4 carbon atoms.
Step 2: Determine the type of functional group present. The structure has a carbonyl group (C=O) which indicates it is a ketone.
Step 3: Number the carbon chain starting from the end closest to the functional group. The carbonyl group is on the second carbon.
Step 4: Combine the name of the carbon chain with the position of the ketone. The longest chain with 4 carbons is called 'butane', and since the ketone is on the second carbon, it is named 'butan-2-one'.
