You're on a roll — The statement in the image is incorrect regarding the name "4-Buten-1-ol". Here's the correction and explanation: 1. Identify the functional groups and determine priority: The compound is CH_2=CH-CH_2-CH_2OH. It contains two functional groups: A hydroxyl group (-OH), which makes it an alcohol. A carbon-carbon double bond (C=C), which makes it an alkene. According to IUPAC rules, the hydroxyl group (-OH) has higher priority than the double bond. 2. Number the carbon chain: The carbon chain must be numbered such that the highest priority functional group (the hydroxyl group) receives the lowest possible number. 4CH_2=3CH-2CH_2-1CH_2OH The hydroxyl group is on carbon 1. The double bond starts at carbon 3 (between carbon 3 and carbon 4). 3. Construct the IUPAC name: The parent chain has 4 carbons, so the base name is "but-". The double bond is at position 3, so it's "but-3-en-". The alcohol group is at position 1, so it's "-1-ol". Combining these, the correct IUPAC name is But-3-en-1-ol. Conclusion: The image correctly identifies that "1-Buten-4-ol" is incorrect because the alcohol group must have the lowest possible number. However, the name "4-Buten-1-ol" is also incorrect because the double bond is at position 3, not 4. The position of a double bond is indicated by the lower-numbered carbon atom involved in the bond. The correct IUPAC name for CH_2=CH-CH_2-CH_2OH is But-3-en-1-ol.
