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

Let’s analyze each compound and determine its IUPAC name<\/strong>.<\/p>\n\n\n\n

1. CH\u2083-CH\u2082-CH\u2082-OH<\/strong><\/h3>\n\n\n\n

This compound consists of a three-carbon chain with a hydroxyl (-OH) functional group<\/strong> attached to the terminal carbon.<\/p>\n\n\n\n

    \n
  • The longest carbon chain has three carbons<\/strong>, meaning the parent name is propane<\/strong>.<\/li>\n\n\n\n
  • The presence of the hydroxyl (-OH) group changes propane \u2192 propanol<\/strong>.<\/li>\n\n\n\n
  • Since the -OH group is on carbon 1<\/strong>, the correct IUPAC name<\/strong> is propan-1-ol<\/strong>.<\/li>\n<\/ul>\n\n\n\n
    \n\n\n\n

    2. CH\u2083-CH\u2082-C(=O)-CH\u2083<\/strong><\/h3>\n\n\n\n

    This compound contains a ketone (-CO) functional group<\/strong>.<\/p>\n\n\n\n

      \n
    • The longest chain has four carbons<\/strong>, meaning the parent name is butane<\/strong>.<\/li>\n\n\n\n
    • The ketone (-CO) group<\/strong> changes butane \u2192 butanone<\/strong>.<\/li>\n\n\n\n
    • The carbonyl (-CO) is on carbon 2<\/strong> (since ketones are assigned the lowest number possible).<\/li>\n\n\n\n
    • Thus, the IUPAC name<\/strong> is butan-2-one<\/strong>.<\/li>\n<\/ul>\n\n\n\n
      \n\n\n\n

      3. CH\u2083-CH\u2082-C(=O)-CH\u2082-CH\u2083<\/strong><\/h3>\n\n\n\n

      This compound contains a ketone (-CO) functional group<\/strong> as well.<\/p>\n\n\n\n

        \n
      • The longest chain consists of five carbons<\/strong> (pentane).<\/li>\n\n\n\n
      • The ketone (-CO) group<\/strong> changes pentane \u2192 pentanone<\/strong>.<\/li>\n\n\n\n
      • The carbonyl (-CO) is at carbon 2<\/strong>.<\/li>\n\n\n\n
      • Thus, the IUPAC name<\/strong> is pentan-2-one<\/strong>.<\/li>\n<\/ul>\n\n\n\n
        \n\n\n\n

        4. CH\u2083-CH\u2082-CH\u2082-CH\u2082-C(=O)-OH<\/strong><\/h3>\n\n\n\n

        This compound has a carboxyl (-COOH) functional group<\/strong>, making it a carboxylic acid<\/strong>.<\/p>\n\n\n\n

          \n
        • The longest chain has five carbons<\/strong> (pentane).<\/li>\n\n\n\n
        • The carboxyl (-COOH) group<\/strong> changes pentane \u2192 pentanoic acid<\/strong>.<\/li>\n\n\n\n
        • The carboxyl (-COOH) is always assigned carbon 1<\/strong>.<\/li>\n\n\n\n
        • The IUPAC name<\/strong> is pentanoic acid<\/strong>.<\/li>\n<\/ul>\n\n\n\n
          \n\n\n\n

          Explanation (300 words)<\/strong><\/h3>\n\n\n\n

          The IUPAC nomenclature system<\/strong> provides a standard method for naming organic compounds. The name of an organic molecule depends on:<\/p>\n\n\n\n

            \n
          1. The longest carbon chain<\/strong> \u2013 Determines the parent name (e.g., methane, ethane, propane, etc.).<\/li>\n\n\n\n
          2. The functional group<\/strong> \u2013 Determines the suffix or priority.<\/li>\n\n\n\n
          3. The numbering of the chain<\/strong> \u2013 Assigns the lowest possible number to the functional group.<\/li>\n<\/ol>\n\n\n\n
              \n
            • Alcohols (-OH):<\/strong> Named with the -ol<\/strong> suffix (e.g., propan-1-ol).<\/li>\n\n\n\n
            • Ketones (-CO-):<\/strong> Named with the -one<\/strong> suffix (e.g., butan-2-one).<\/li>\n\n\n\n
            • Carboxylic acids (-COOH):<\/strong> Named with the -oic acid<\/strong> suffix (e.g., pentanoic acid).<\/li>\n<\/ul>\n\n\n\n

              For alcohols, the position of the hydroxyl (-OH) is indicated with a number. For ketones, numbering ensures the carbonyl (-CO) group<\/strong> gets the lowest number. Carboxylic acids always have priority<\/strong> over other groups, and the -COOH group is always at carbon 1.<\/p>\n\n\n\n

              Correct IUPAC names ensure clear communication and avoid ambiguity in chemical identification.<\/p>\n\n\n\n

              Now, I will generate an image<\/strong> of the molecular structures.<\/p>\n\n\n\n
