Questions & Step-by-Step Solutions
What is the IUPAC name for the compound CH₃-CH₂-CH(CH₃)-CH₂OH?
Step 1: Identify the structure of the compound CH₃-CH₂-CH(CH₃)-CH₂OH. This shows that there are carbon (C) and hydrogen (H) atoms, and a hydroxyl group (OH).
Step 2: Count the number of carbon atoms in the longest continuous chain. In this case, there are 5 carbon atoms: CH₃-CH₂-CH(CH₃)-CH₂.
Step 3: Determine the position of the hydroxyl group (OH). The OH group is attached to the second carbon in the chain.
Step 4: Use the IUPAC naming rules. Since there are 5 carbons in the longest chain, the base name is 'pentane'.
Step 5: Add the position of the hydroxyl group to the name. Since the OH is on the second carbon, we name it '2-pentanol'.
Step 6: Combine the information to conclude that the IUPAC name for the compound is 2-pentanol.
