Q
Q: What is the IUPAC name for the compound with the structure CH3-CH2-CH(CH3)-CH2-Br?
Solution: The longest carbon chain has four carbons, and the bromine is on the second carbon, making the correct IUPAC name 2-bromo-3-methylbutane.
Steps: 8
Step 1: Identify the longest carbon chain in the compound. Count the number of carbon atoms in the chain.
Step 2: In the structure CH3-CH2-CH(CH3)-CH2-Br, the longest chain has 4 carbon atoms.
Step 3: Name the longest chain. A chain with 4 carbon atoms is called 'butane'.
Step 4: Identify the substituents (groups attached to the main chain). Here, there is a bromine (Br) and a methyl (CH3) group.
Step 5: Determine the position of the bromine atom. It is attached to the second carbon in the chain.
Step 6: Determine the position of the methyl group. It is attached to the third carbon in the chain.
Step 7: Combine the names and positions of the substituents with the name of the longest chain. The bromine is at position 2 and the methyl group is at position 3.
Step 8: Write the final IUPAC name as '2-bromo-3-methylbutane'.
