Boiling Points of Alcohols. The oxygen in alcohols and phenols is sp 3 hybridized which gives the roughly the same tetrahedral geometry as water. The bond angle of methanol (108.5 o) is slightly less than the tetrahedral value mainly due to the presence of its lone pair electrons.
15 Σεπ 2022 · Explain why the boiling points of alcohols are higher than those of ethers and alkanes of similar molar masses. Explain why alcohols and ethers of four or fewer carbon atoms are soluble in water while comparable alkanes are not soluble.
Explain why the boiling points of alcohols are higher than those of ethers and alkanes of similar molar masses. Explain why alcohols and ethers of four or fewer carbon atoms are soluble in water while comparable alkanes are not soluble.
The boiling point of an alcohol is always significantly higher than that of the analogous alkane. The boiling points of the alcohols increase as the number of carbon atoms increases. The patterns in boiling point reflect the patterns in intermolecular attractions.
The boiling points of alcohols are much higher than those of alkanes with similar molecular weights. For example, ethanol, with a molecular weight (MW) of 46, has a boiling point of 78 °C (173 °F), whereas propane (MW 44) has a boiling point of −42 °C (−44 °F).
29 Ιουλ 2024 · This boiling point calculator tells you how to calculate the boiling point of most common substances at an arbitrary pressure, based on the Clausius–Clapeyron relation. Whether you want to analyze water, ethanol, or ammonia, simply provide some reference values, and this calculator will do the work for you.
