Q: What is the IUPAC name for the compound with the formula C4H9-CO-CH3?
Solution: The compound is a ketone with a four-carbon chain, thus it is Butan-2-one.
Steps: 6
Step 1: Identify the functional group in the compound. The formula C4H9-CO-CH3 indicates that there is a carbonyl group (C=O), which means it is a ketone.
Step 2: Count the total number of carbon atoms in the longest chain. The compound has a total of 5 carbon atoms (4 from C4H9 and 1 from CH3).
Step 3: Determine the position of the carbonyl group. The carbonyl group is located between the 4-carbon chain (C4H9) and the methyl group (CH3), making it a ketone at the second carbon.
Step 4: Name the longest carbon chain. The longest chain has 4 carbon atoms, which is called 'butane'.
Step 5: Indicate the position of the carbonyl group in the name. Since the carbonyl group is on the second carbon, we name it 'butan-2-one'.
Step 6: Combine the information to get the final IUPAC name: Butan-2-one.
