At 0:00:00 the video opens with an introduction to single‑molecule alcohols. At 0:04:30 it explains the classification of alcohols, followed by a discussion of their structural basis in hydrocarbons at 0:06:06. The next segment at 0:09:01 focuses on the number of hydroxyl groups, while 0:09:50 examines the nature of the carbon atom bonded to the hydroxyl group. At 0:10:36 the classification is summarized, and at 0:12:31 the concept of limiting single‑molecule alcohols is introduced. The video then covers trivial nomenclature at 0:16:31 and isomerism at 0:19:24. At 0:25:10 the hydrogen bonding of alcohols is discussed, followed by their chemical properties at 0:28:00 and acidic properties at 0:29:10. The narrative continues with substitution reactions: hydrogen replacement in the hydroxyl group at 0:33:20, halogen substitution at 0:42:40, and amine substitution at 0:48:45. At 0:51:01 the process of etherification is described. The next section at 1:05:59 covers intramolecular dehydration, followed by intermolecular dehydration at 1:10:01. At 1:16:52 the overall dehydrogenation of alcohols is presented. The video then discusses the genetic link between organic matter and alcohols at 1:22:00, and oxidation reactions at 1:24:30. Subsequent oxidation of primary alcohols occurs at 1:25:12, secondary at 1:26:10, and the specific oxidation of alcohols with KMnO₄ in acidic medium at 1:26:54, with K₂Cr₂O₇ in acidic medium at 1:33:27, with KMnO₄ in basic medium at 1:39:30, with KMnO₄ in neutral medium at 1:45:26, and with CuO at 1:50:52. At 1:54:13 the chemical properties of single‑molecule alcohols are summarized. The methods of obtaining alcohols are discussed at 1:57:37, including the hydration of alkenes, and the recovery of alkanes and ketones at 1:58:40. The hydrolysis of complex ethers is presented at 2:00:35, followed by basic hydrolysis of monohalogenated compounds at 2:03:02. At 2:05:31 the interaction of halogenated compounds with bases is examined, and at 2:06:03 specific methods of obtaining alcohols are described. The unique properties of ethanol are highlighted at 2:07:16, and the narrative concludes with a summary of the methods for obtaining single‑molecule alcohols at 2:07:35, followed by answers to questions at 2:08:00.
