Step 1: Identify the molecular formula C3H6O. Count the number of carbon (C), hydrogen (H), and oxygen (O) atoms.
Step 2: Determine the type of compound based on the formula. Since it has a carbonyl group (C=O) and is an aldehyde (the carbonyl is at the end of the carbon chain), it is classified as an aldehyde.
Step 3: Count the number of carbon atoms in the longest chain. There are 3 carbon atoms in C3H6O.
Step 4: Use the naming convention for aldehydes. The name is based on the number of carbon atoms. For 3 carbons, the prefix is 'prop'.
Step 5: Add the suffix for aldehydes, which is 'al'. Combine the prefix and suffix to get the name 'Propanal'.
