Ethanol has a boiling point of 78.37°C, while glycerol has a higher boiling point of 290°C. This difference is due to the presence of more hydrogen bonding sites in glycerol compared to ethanol, resulting in stronger intermolecular forces that require more energy to break during boiling.

What is the technique used to separate ethanol from a mixture of ethanol and propanol?
Fractional distillation can be used to separate ethanol from a mixture of ethanol and propanol. This technique takes advantage of the differences in boiling points of the two compounds to separate them based on their vapor pressures. Ethanol has a lower boiling point than propanol, allowing it to vaporize first and be collected separately.
What substance has a boiling point of 78 degrees celsius?
Ethanol has a boiling point of 78 degrees Celsius.
What is the boiling point of ethanol at 30.9 in HG?
The boiling point of ethanol at 30.9 inHg is approximately 67 degrees Celsius.
Boiling point of ethanol?
The boiling point of ethanol is approximately 78.37 degrees Celsius or 173.07 degrees Fahrenheit at standard atmospheric pressure.
What has a higher boiling point alcohol or water?
Water has a higher boiling point than alcohol. The boiling point of water is 100°C, while the boiling point of alcohol (such as ethanol) is lower, around 78°C.
Boiling point ethanol?
The boiling point of ethanol is 78.37 degrees Celsius (173.07 degrees Fahrenheit).
What effect does adding water have on the boiling point of ethanol?
Adding water to ethanol lowers its boiling point. This is because water forms an azeotrope with ethanol, which alters the vapor pressure of the mixture, resulting in a lower boiling point compared to pure ethanol.
Why does the boiling point of methylated spirits drop?
The boiling point of methanol is lower than the boiling point of ethanol.
What is the normal boiling point of ethanol?
The boiling point of ethanol whose boiling point is 78.3 degrees Celsius at 760 mm Hg at 650 mm Hg is going to be 75 degrees Celsius. This calculation is done using the clausius-clapeyron equation.
Which is a better solvent for boiling point elevation ethanol or water?
Ethanol is a better solvent for boiling point elevation compared to water. This is because ethanol has a higher boiling point than water. When a solute is added to ethanol, it will raise the boiling point of the solution more significantly than if the same solute were added to water.

Ethanol c2h5oh and methyl ether ch3och3 have the same molar mass.W hich has a higher boiling point?
Ethanol (C2H5OH) has a higher boiling point compared to methyl ether (CH3OCH3) due to hydrogen bonding in ethanol. Hydrogen bonding results in stronger intermolecular forces in ethanol, requiring more energy to overcome, hence a higher boiling point.
Does ethanol has the lower boiling point?
It depends what chemical or compound you are comparing the boiling point to. Ethanol has an atmospheric pressure boiling point of 78.1 °C (172.6 °F). This is slightly lower than the boiling point of water at the same pressure, much lower than the boiling point of iron, much higher than the boiling point of bromine.
Why is the boiling point of glycerol higher than that of 1-pentanol?
The higher boiling point of glycerol compared to 1-pentanol is due to stronger intermolecular forces in glycerol. Glycerol can form hydrogen bonds with other glycerol molecules, leading to increased attraction and a higher boiling point. 1-pentanol has weaker van der Waals forces between its molecules, resulting in a lower boiling point.
What substance has a boiling point of 78 degrees celsius?
Ethanol has a boiling point of 78 degrees Celsius.
Which has higher boiling point oxygen or ethanol?
Oxygen.
What effect does ethanol have on the boiling point of water?
The pure ethanol has the boiling point 78.5 celsius while water has 100 celsius so when water is added to ethanol its boiling point becomes increased.
