NettetIn short, an alcohol is composed of at least one oxygen and hydrogen group, a carbon atom and then another carbon and/or a hydrogen. The structure of an alcohol is … NettetPentane has five carbons, one, two, three, four, five, so five carbons for pentane. And pentane has a boiling point of 36 degrees Celsius. Hexane has six carbons, one, two, three, four, five, and six. So six carbons, and a higher boiling point, of 69 degrees C. Let's draw in another molecule of pentane right here. NettetThe structural formula for ethanol, C 2 H 5 OH, provides a bit additional information, indicating that the two-carbon chain has a hydroxyl group (-OH) at the end. Properties of Ethanol At room temperature, Ethanol is always a liquid, and it has a melting point of 156K and a boiling point of 351 K. smiths lane display village
