Q: What is the correct IUPAC name for the compound with the structure CH3-CH(CH3)-CH2-CHO?
Solution: The longest carbon chain has four carbons with an aldehyde group, making it 2-Methylbutanal.
Steps: 6
Step 1: Identify the longest carbon chain in the compound. Count the number of carbon atoms in the chain.
Step 2: The longest chain has 4 carbon atoms, which is called butane.
Step 3: Look for any functional groups. The compound has an aldehyde group (-CHO) at the end of the chain.
Step 4: Since the aldehyde group is present, the compound is classified as an aldehyde, specifically butanal.
Step 5: Check for any branches in the carbon chain. There is a methyl group (CH3) attached to the second carbon of the chain.
Step 6: Name the compound by combining the branch name and the main chain name. The methyl group is on the second carbon, so we name it 2-Methylbutanal.
