The Correct Answer and Explanation is :<\/strong><\/mark><\/p>\n\n\n\n

To determine which compound matches the IR spectrum, we need to analyze the specific functional groups and bonds present in the spectrum and match them to the corresponding compounds. Since I cannot directly view the image you provided, I will guide you through how to identify the compound based on a typical IR spectrum and its features.<\/p>\n\n\n\n

In an IR spectrum, you typically observe the following key regions:<\/p>\n\n\n\n

    \n
  1. Stretching Frequencies<\/strong>:<\/li>\n<\/ol>\n\n\n\n
      \n
    • O-H Stretch (Alcohols, Phenols)<\/strong>: A broad, strong peak around 3200-3550 cm\u207b\u00b9.<\/li>\n\n\n\n
    • C-H Stretch (Alkanes)<\/strong>: A sharp peak around 2800-3000 cm\u207b\u00b9.<\/li>\n\n\n\n
    • C=O Stretch (Carbonyl compounds)<\/strong>: Strong peak near 1700 cm\u207b\u00b9.<\/li>\n\n\n\n
    • C=C Stretch (Alkenes)<\/strong>: A weak to moderate peak near 1600 cm\u207b\u00b9.<\/li>\n<\/ul>\n\n\n\n
        \n
      1. Fingerprint Region<\/strong>: This is typically from 600-1400 cm\u207b\u00b9, where many individual compounds have unique absorptions.<\/li>\n<\/ol>\n\n\n\n

        Now, let’s evaluate the compounds in the list based on these features:<\/p>\n\n\n\n

          \n
        1. Dipropyl Ether<\/strong>: The key features are the C-H stretch around 2800 cm\u207b\u00b9 and the ether group, which would give a C-O stretch around 1050 cm\u207b\u00b9.<\/li>\n\n\n\n
        2. Cyclohexane<\/strong>: Cyclohexane will have typical alkane C-H stretches around 2900 cm\u207b\u00b9 and might show no significant functional group absorption.<\/li>\n\n\n\n
        3. 1,5-Hexadiene<\/strong>: This compound will show alkene C-H stretches and a C=C stretch around 1600 cm\u207b\u00b9.<\/li>\n\n\n\n
        4. 3-Hexanol<\/strong>: This will show an O-H stretch (broad around 3300 cm\u207b\u00b9) and a C-H stretch from the alkane region.<\/li>\n\n\n\n
        5. 1-Hexen-3-Ol<\/strong>: Like 3-hexanol, it would show both an O-H stretch and a C=C stretch around 1600 cm\u207b\u00b9.<\/li>\n\n\n\n
        6. Trans-4-Octene<\/strong>: Will show a C=C stretch and typical alkene stretches, likely in the 1600 cm\u207b\u00b9 region.<\/li>\n\n\n\n
        7. 1-Methylcyclopentene<\/strong>: This compound will show an alkene stretch and C-H stretches, likely with the characteristic C=C peak around 1600 cm\u207b\u00b9.<\/li>\n<\/ol>\n\n\n\n

          Based on the characteristics of the IR spectrum you described (assuming the spectrum includes a broad O-H stretch and a C=C stretch), 3-Hexanol<\/strong> or 1-Hexen-3-Ol<\/strong> would be the most likely matches, as both contain both an alcohol group and an alkene, showing distinct IR absorptions for those functional groups.<\/p>\n\n\n\n
