the Molecular Structure of Water (H₂O) is a polar molecule with a bent shape, consisting of two hydrogen atoms and one oxygen atom. Butane (C₄H₁₀), on the other hand, is a nonpolar molecule composed of four carbon atoms bonded to ten hydrogen atoms. The polar nature of water molecules allows them to form stronger intermolecular forces compared to the nonpolar butane molecules.
Intermolecular Forces: Water molecules are held together by hydrogen bonds, which are relatively strong electrostatic attractions between the positively charged hydrogen atom of one water molecule and the negatively charged oxygen atom of another water molecule. These hydrogen bonds require more energy to break, resulting in a higher boiling point for water. Butane molecules are held together by weaker van der Waals forces, which are temporary dipole-dipole interactions between nonpolar molecules. As a result, butane boils at a lower temperature compared to water.

Water boils at a higher temperature than butane due to the differences in the strength of intermolecular forces between the molecules of each substance.
Water molecules are held together by strong hydrogen bonds, which are electrostatic attractions between the positively charged hydrogen atoms of one water molecule and the negatively charged oxygen atom of another water molecule. These hydrogen bonds are relatively strong and require a significant amount of energy to break, leading to a higher boiling point for water.
On the other hand, butane molecules are held together by weaker van der Waals forces, specifically London dispersion forces. These forces arise from temporary fluctuations in electron distribution, creating temporary dipoles that induce dipoles in neighboring molecules.
The London dispersion forces between butane molecules are weaker than the hydrogen bonds in water, requiring less energy to overcome and leading to a lower boiling point for butane.
The difference in boiling points also reflects the molecular weights of the substances.
Water (H2O) has a higher molecular weight than butane (C4H10), and generally, substances with higher molecular weights tend to have higher boiling points due to increased intermolecular forces.
In summary, the stronger hydrogen bonding and higher molecular weight of water compared to the weaker van der Waals forces in butane contribute to water having a higher boiling point than butane.

∙ 10y agoDue to strong molecular bonds between H2O (the formula for water) so it is hard to break the bonds. That is why water boils at a higher temperature than butane

Will rainwater and sea water boil at the same temperature?
Sea water will boil at higher temp
Why does beer boil at a lower temperature than tap water?
Beer boil at a higher temperature than tap water because contain many solutes.
What temperature does salt water boil at?
Depends on how much and what salt, but definitely higher than pure water.
When salt is added to boiling water at 100 degrees Celsius will the water boil faster or slower?
Slower, at higher temperature that is.
Does sea water boil at higher temperature than tap water and why?
Yes. Dissolved substances increased the boiling point.
Will rainwater and sea water boil at the same temperature?
Sea water will boil at higher temp
Why does beer boil at a lower temperature than tap water?
Beer boil at a higher temperature than tap water because contain many solutes.
Why does water boil at a higher temperature in a pressure cooker?
less than 100oC.
Does water boil the same at sea level as it does at higher elevations?
Due to lower atmospheric pressure at altitude, water will boil at lower temperature.
Does water boil faster if it contains salt?
Salty water boils at a higher temperature than pure water does.
Why is the temperature of the boiling water higher than the temperature of an ordinary top water?
When you boil water, the velocity of moving molecules in water gets increased so as the intermolecular energy of water. For that the temperature of hot water is higher then normal or cold water.
When water boils its temperature?
The boiling point of water is 100 degrees Celsius or 212 degrees Fahrenheit. However, water boils at a lower temperature at higher altitude. Salt water boils at a higher temperature than pure water.
Why the sea water boil at a slightly higher temperature than water from from a freshwater lake?
The salt acts as a catalyst which prevents the water from boiling at the lower temperature.
What temperature does salt water boil at?
Depends on how much and what salt, but definitely higher than pure water.
Why is it harder to boil water with salt?
It's not "harder", it just requires a slightly higher temperature.
Why does sugar water boil at a different temperature then normal water?
Sugar has a higher boiling temperature than that of water, so water with sugar dissolved into it will take more energy and raise to a higher temp before boiling.
Can you boil the water at room temperature?
yes,at room temperature by decreasing the pressure we can boil the water.
