Q: What is the IUPAC name of the compound with the formula C2H5-CO-CH3?
Solution: The compound is a ketone with four carbons, and the carbonyl group is on the second carbon, thus it is Butan-2-one.
Steps: 6
Step 1: Identify the formula of the compound, which is C2H5-CO-CH3.
Step 2: Break down the formula. C2H5 is an ethyl group (2 carbons), CO is a carbonyl group (C=O), and CH3 is a methyl group (1 carbon).
Step 3: Count the total number of carbon atoms in the compound. There are 2 (from C2H5) + 1 (from CO) + 1 (from CH3) = 4 carbon atoms.
Step 4: Determine the type of compound. Since there is a carbonyl group (C=O) between two carbon chains, it is a ketone.
Step 5: Number the carbon atoms starting from the end closest to the carbonyl group. The carbonyl group is on the second carbon.
Step 6: Name the compound based on the number of carbon atoms and the position of the carbonyl group. With 4 carbons and the carbonyl on the second carbon, the name is Butan-2-one.
