What is the IUPAC name for CH3-CH2-CH2-CHO? (2020)
Step 1: Identify the longest carbon chain in the molecule. In CH3-CH2-CH2-CHO, the longest chain has 4 carbon atoms.
Step 2: Count the number of carbon atoms in the chain. There are 4 carbon atoms.
Step 3: Determine the functional group. The 'CHO' at the end indicates that this molecule has an aldehyde functional group.
Step 4: Use the IUPAC naming rules. For a 4-carbon chain with an aldehyde, the name is based on the root 'but' (for 4 carbons) and ends with 'anal' (for aldehyde).
Step 5: Combine the root and suffix to get the final name. The IUPAC name is Butanal.
