Q: What is the IUPAC name for the compound with the formula C5H10O that has a carbonyl group on the second carbon?
Solution: The compound is a ketone with the carbonyl group on the second carbon, making it 2-pentanone.
Steps: 5
Step 1: Identify the molecular formula, which is C5H10O. This indicates that the compound has 5 carbon atoms, 10 hydrogen atoms, and 1 oxygen atom.
Step 2: Determine the type of compound. Since there is a carbonyl group (C=O) and it is not at the end of the carbon chain, it is a ketone.
Step 3: Count the total number of carbon atoms in the longest chain. There are 5 carbon atoms, so the base name will be 'pentane'.
Step 4: Identify the position of the carbonyl group. The problem states that the carbonyl group is on the second carbon, so we will use the number '2' to indicate this position.
Step 5: Combine the information to form the IUPAC name. The name is '2-pentanone', where '2-' indicates the position of the carbonyl group and 'pentanone' indicates it is a ketone with 5 carbons.
