Questions & Step-by-Step Solutions
What is the IUPAC name for the compound with the structure CH3-CH(CH3)-CH2-CHO?
Step 1: Identify the longest continuous chain of carbon atoms in the structure. In this case, the longest chain has four carbon atoms.
Step 2: Determine the functional group present. The structure has an aldehyde group (-CHO) at the end of the longest chain.
Step 3: Number the carbon atoms in the longest chain starting from the end closest to the functional group. This gives the aldehyde the lowest possible number.
Step 4: Identify any branches or substituents on the longest chain. There is a methyl group (CH3) attached to the second carbon.
Step 5: Combine the information to name the compound. The longest chain is a butane (4 carbons), and there is a methyl group on the second carbon, making it 2-Methylbutanal.
