The correct answer is that the given formulas accurately represent the molecular structure of the first six alcohols in the homologous series of alkanols. Alcohols are organic compounds characterized by the presence of a hydroxyl group (-OH) attached to a saturated carbon chain. The general formula for a straight-chain alcohol can be expressed as CₙH₂ₙ₊₁OH, where n represents the number of carbon atoms.
Methanol is the simplest alcohol, consisting of one carbon atom bonded to three hydrogen atoms and a hydroxyl group. Ethanol follows with a two-carbon chain, making it the primary alcohol found in alcoholic beverages. Propanol consists of three carbon atoms, with a hydroxyl group attached to either the first or second carbon, leading to structural isomers such as 1-propanol and 2-propanol. Butanol extends the chain to four carbon atoms, exhibiting different isomeric forms that influence its physical properties and applications. Pentanol and hexanol continue this pattern, increasing the molecular weight and altering characteristics such as boiling point and solubility.
The length of the carbon chain significantly impacts the physical and chemical properties of alcohols. Short-chain alcohols, such as methanol and ethanol, are highly miscible with water due to their ability to form hydrogen bonds. As the chain length increases, the hydrophobic nature of the alkyl group becomes more pronounced, reducing solubility in water while enhancing interactions with nonpolar solvents.
Alcohols serve various purposes in industrial and biological contexts. Methanol is widely used as a solvent and fuel, ethanol is prominent in fermentation and pharmaceutical formulations, and longer-chain alcohols play roles in the manufacture of perfumes, detergents, and plasticizers. The ability of alcohols to undergo oxidation, dehydration, and esterification further broadens their applications in organic synthesis and biochemical pathways.
