Q: What is the correct IUPAC name for the compound CH3-CH(CH3)-CH2-CHO?
Solution: The longest carbon chain has four carbons, and the aldehyde is at the end, making it 2-methylbutanal.
Steps: 5
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 branches or substituents on the main chain. In this case, there is a methyl group (CH3) attached to the second carbon.
Step 4: Since the compound has an aldehyde group (CHO) at the end of the chain, it is named as an aldehyde.
Step 5: Combine the information: The longest chain is butane, there is a methyl group on the second carbon, and it is an aldehyde. This gives us the name 2-methylbutanal.
