Q: What is the IUPAC name of the compound with the formula C5H10O that contains a ketone functional group?
Solution: The compound is a ketone with five carbon atoms. The longest carbon chain is pentane, and the ketone group is on the second carbon, making it 2-Pentanone.
Steps: 6
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 that the compound contains a ketone functional group. Ketones have the structure R-CO-R', where R and R' are carbon chains.
Step 3: Count the number of carbon atoms in the longest chain. Since there are 5 carbon atoms, the longest chain is called pentane.
Step 4: Identify the position of the ketone group. In a ketone, the carbonyl (C=O) group is located between two carbon atoms. For 5 carbon atoms, the ketone can be on the 2nd or 3rd carbon.
Step 5: Choose the lowest number for the ketone position. The ketone group is on the 2nd carbon, so we name it 2-Pentanone.
Step 6: Combine the information to write the IUPAC name: 2-Pentanone.
