Octane is a straight chain molecule with a large surface area and stacks easily with other octane molecules. This increases the strength of the London dispersion forces that keep the octane molecules attracted to each other. The London dispersion forces on octane are greater than for smaller straight chain molecules because octane is both heavier and has more electrons that make it more polarizable.

∙ 12y agoBecause octane has more carbons, and the more carbons you have the higher the melting point. also octane is a gas that is very close to nonane (which is the first liquid) and that would mean it has a larger boiling point that methane (which is a gas that is the first one CH4). that is why octane has a larger boiling point that methane. Also, you can also figure it out the boiling points of each and look at the differences.

What is the relationship between the altitude and the boiling point?
The boiling point of water will be greatest at that point on Earth that is the closest to sea level. Boiling point of water depends on the atmospheric pressure. The boiling point of water varies depending on the weather. At low atmospheric temperatures due to weather or due to being up a mountain, the water will boil below its "normal" boiling point of 100 oC
What is the boiling point degrees in Fahrenheit?
At sea level the boiling temperature of water is 212o Fahrenheit. At different air pressures the boiling temperature changes. Higher air pressures require higher temperatures to boil. For example, if you go to a mountain top you could lower air pressure until water could boil at say 99o Fahrenheit. If you change substances, from water to something else, that substance would have its own individual boiling temperature, the point at which it changes from liquid to gas.
As you go to higher elevations above sea level the boiling point of water?
as you go higher above sea level, pressure decreases. Due to the decrease in pressure, the temperature needed for water to boil is less than it is than it would be at sea level. Thus, it would take less heat energy for the bonds to break and become a gas than it would in an environment with more pressure.
What effcet does altitude have on boiling point of water?
Higher altitude decreases the boiling point of water. Boiling point is defined as the point at which the vapour pressure of the substance above the liquid is equal to the external atmospheric pressure. Since the external atmospheric pressure is lower at higher altitudes, a lower vapour pressure of water is required for water to boil and therefore a lower temperature is required to achieve the desired vapour pressure.
Does the amount of substance affect its boiling point?
Hydrogen bonding is the strongest intermolecular attractive force. It causes the boiling point to be elevated since the molecules are more attracted to each other and thus require more energy to break from the liquid phase.
Who would use octane gas the most?
Octane is a liquid, not a gas. Its boiling point is considerably higher than that of water.
What effect does salt have on hot water?
Salt raises the boiling point of water. The process is known as boiling point elevation. The higher the concentration of salt in the water, the higher the boiling point of water is raised.
Which substance would have a higher boiling point sodium chloride or water?
Sodium chloride has a higher boiling point.
A student measures the boiling point of rainwater and sea water.Which has the higher boiling point?
Sea water has higher boiling point,as it contains sodium chloride
The normal boiling point of chloroform which has a higher vapor pressure than water at 100 degrees celsius is?
higher then the normal boiling point of water
What factor besides the temperature affects the boiling point of water?
Air pressure also affects the boiling point of water. The higher the air pressure, the higher the boiling point.
How does the boiling point in degrees Celsius of a saltwater solution compare to the boiling point of normal tap water?
The boiling point of salt water will be higher - whichever scale is used to measure the temperature. How much higher will depend on the amount of salt that is dissolved in the water.
How does pressure affect boiling point?
The boiling point is that temperature when the SATURATEDvapor pressure of a liquidbecomes equal tothe surrounding pressure.Thus the higher the sorrounding pressure, the higher the boiling point.
What is the boiling point of treacle?
alot higher that water
The boiling point of water in Nevada?
It depends where you are in Nevada. The boiling point will be lower in areas at a higher elevation.
What has a higher boiling point alcohol or water?
Water has a higher boiling point that alcohol (ethanol). The main reason for this is because water has stronger intermolecular forces holding the molecules together.
Is the boiling point of water higher than the boiling point of water?
physiological answers tell us that In neurology water may be boiling at a lower substantial rate then non water water.
