What is the IUPAC name of the compound with the formula C3H6O?

What is the IUPAC name of the compound with the formula C3H6O?

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 present in the compound. Since there is a carbonyl group (C=O) and the formula fits the structure of a ketone, we identify it as a ketone.
Step 3: Count the carbon atoms in the longest carbon chain. There are 3 carbon atoms, so the base name will be 'propane'.
Step 4: Identify the position of the carbonyl group. In this case, the carbonyl group is on the second carbon, which gives us 'propan-2-one'.
Step 5: Combine the base name and the functional group to get the IUPAC name: Propan-2-one.
