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

The compound with the highest boiling point<\/strong> among the given structures is the second compound<\/strong>:<\/p>\n\n\n\n

CH\u2083CH\u2082\u2013CH(OH)\u2013CH\u2082CH\u2083<\/strong><\/p>\n\n\n\n

Correct Answer: The second<\/strong> compound (alcohol group \u2013OH)<\/h3>\n\n\n\n

Explanation:<\/h3>\n\n\n\n

Boiling point is largely influenced by intermolecular forces<\/strong>. The stronger the forces between molecules, the more energy (and thus a higher temperature) is needed to separate them into the gas phase. Let’s examine the intermolecular forces present in each compound:<\/p>\n\n\n\n

\n\n\n\n

1. CH\u2083CH\u2082\u2013CH(CH\u2083)\u2013CH\u2082CH\u2083<\/strong><\/h4>\n\n\n\n
    \n
  • This is a branched alkane.<\/li>\n\n\n\n
  • It exhibits only London dispersion forces<\/strong>, which are the weakest.<\/li>\n\n\n\n
  • Lowest boiling point<\/strong> among the options.<\/li>\n<\/ul>\n\n\n\n
    \n\n\n\n

    2. CH\u2083CH\u2082\u2013CH(OH)\u2013CH\u2082CH\u2083<\/strong><\/h4>\n\n\n\n
      \n
    • This is a secondary alcohol<\/strong>.<\/li>\n\n\n\n
    • It exhibits hydrogen bonding<\/strong>, which is the strongest type of intermolecular force among the options here.<\/li>\n\n\n\n
    • Therefore, this compound will have the highest boiling point<\/strong>.<\/li>\n<\/ul>\n\n\n\n
      \n\n\n\n

      3. CH\u2083CH\u2082\u2013CH(Cl)\u2013CH\u2082CH\u2083<\/strong><\/h4>\n\n\n\n
        \n
      • This is a chloroalkane<\/strong>.<\/li>\n\n\n\n
      • Chlorine is electronegative, so it introduces dipole-dipole interactions<\/strong>, which are stronger than London forces but weaker than hydrogen bonding.<\/li>\n\n\n\n
      • Moderate boiling point.<\/li>\n<\/ul>\n\n\n\n
        \n\n\n\n

        4. CH\u2083CH\u2082CH\u2082\u2013O\u2013CH\u2082CH\u2083<\/strong><\/h4>\n\n\n\n
          \n
        • This is an ether<\/strong>.<\/li>\n\n\n\n
        • It has dipole-dipole interactions due to the oxygen, but it does not<\/strong> form hydrogen bonds as there is no \u2013OH group.<\/li>\n\n\n\n
        • Boiling point is higher than alkanes, but lower than alcohols.<\/li>\n<\/ul>\n\n\n\n
          \n\n\n\n

          Conclusion:<\/h3>\n\n\n\n

          Because of the presence of a hydroxyl (\u2013OH) group that enables hydrogen bonding<\/strong>, the second compound<\/strong> (CH\u2083CH\u2082\u2013CH(OH)\u2013CH\u2082CH\u2083) has the strongest intermolecular forces<\/strong> and hence the highest boiling point<\/strong>.<\/p>\n\n\n\n
