Q: What is the correct IUPAC name for the compound CH3-CH2-CH(CH3)-OH?
Solution: The correct IUPAC name for CH3-CH2-CH(CH3)-OH is 2-Methyl-1-propanol, as the longest chain has three carbons and the hydroxyl group is on the first carbon.
Steps: 6
Step 1: Identify the longest carbon chain in the compound. In CH3-CH2-CH(CH3)-OH, the longest chain has three carbon atoms.
Step 2: Number the carbon atoms in the longest chain starting from the end closest to the hydroxyl (OH) group. This gives us 1, 2, and 3.
Step 3: Identify the position of the hydroxyl (OH) group. It is on the first carbon (C1).
Step 4: Identify any substituents on the longest chain. There is a methyl (CH3) group on the second carbon (C2).
Step 5: Combine the information to name the compound. The substituent (methyl) is on carbon 2, and the main chain is a propanol (3 carbon alcohol) with the hydroxyl group on carbon 1.
Step 6: Write the final IUPAC name as 2-Methyl-1-propanol.
