Q
Q: What is the correct IUPAC name for the compound with the structure CH3-CH(CH3)-CH2-CH3?
Solution: The longest chain has four carbons, and there is a methyl group on the second carbon, making it 2-methylbutane.
Steps: 6
Step 1: Identify the longest continuous chain of carbon atoms in the structure CH3-CH(CH3)-CH2-CH3.
Step 2: Count the number of carbon atoms in the longest chain. In this case, there are four carbon atoms.
Step 3: Number the carbon atoms in the longest chain starting from one end. The numbering will be: 1 (CH3), 2 (CH), 3 (CH2), 4 (CH3).
Step 4: Look for any branches (substituents) on the main chain. There is a methyl group (CH3) attached to the second carbon.
Step 5: Combine the information: The longest chain is a butane (4 carbons) and there is a methyl group on the second carbon.
Step 6: Write the IUPAC name by placing the number of the carbon with the substituent before the name of the longest chain. The name is 2-methylbutane.
