    Question

    Which is the correct IUPAC name for

    CH₃CH₂CH(CH₃)CH₂OH?
    A 3-methyl-1-butanol Correct Answer Incorrect Answer
    B 2-methylbutan-1-ol Correct Answer Incorrect Answer
    C 2-methyl-1-butanol Correct Answer Incorrect Answer
    D 1-butanol Correct Answer Incorrect Answer

    Solution

    Identify the longest carbon chain including the –OH (alcohol) group: The longest chain with the –OH group has 4 carbon atoms, so the parent chain is butanol. Number the chain starting from the end nearest to the –OH group: Numbering from the –OH side: Carbon 1 → CH₂OH Carbon 2 → CH₂ Carbon 3 → CH(CH₃) → methyl group on C-3 Substituent: A methyl group is attached to carbon 3. Therefore, the correct IUPAC name is: 3-methyl-1-butanol
