What is the IUPAC name for the compound with the formula C3H6O?
Correct Answer: propan-2-one
- Step 1: Identify the molecular formula C3H6O. This means the compound has 3 carbon atoms, 6 hydrogen atoms, and 1 oxygen atom.
- Step 2: Determine the functional group. The presence of the oxygen atom suggests it could be an alcohol, ether, aldehyde, or ketone.
- Step 3: Since the formula has a carbonyl group (C=O) and there are no terminal hydrogens, it indicates that the compound is a ketone.
- Step 4: Count the carbon atoms in the longest chain. There are 3 carbon atoms, so the base name is 'propane'.
- Step 5: Identify the position of the carbonyl group. In this case, the carbonyl group is on the second carbon, so we use 'propan-2-one' as the name.
- Step 6: Combine the information to conclude that the IUPAC name for C3H6O is propan-2-one.
