Predominantly its higher molecular mass. The higher mass of a molecule of C5H12 requires more energy to cause it to move fast enough to escape its intermolecular bonding than does the lower mass C2H6 molecule. The intermolecular bonding itself may be stronger in the higher molecular mass molecule, but this is relatively minor compared with the difference in molecular mass.
Not necessarily. Viscosity and boiling point are two separate properties of a compound. Viscosity is a measure of a liquid's resistance to flow, while boiling point is the temperature at which a substance changes from a liquid to a gas. While there may be some correlation between viscosity and boiling point for certain compounds, it is not a direct relationship.
The separation method that includes evaporation is known as simple distillation. Simple distillation involves heating a liquid mixture to separate compounds based on differences in their boiling points. The higher boiling compound evaporates first, leaving behind the lower boiling compound.
The boiling point of a compound is influenced by various factors, including intermolecular forces and molecular weight, and cannot be accurately predicted solely based on the boiling points of elements in it. The presence of functional groups and molecular structure also play a significant role in determining the boiling point of a compound.
Ionic compounds do not have a specific boiling temperature as it depends on the specific compound. The boiling point of an ionic compound will generally be higher than that of covalent compounds due to the strong electrostatic forces between the ions.
The higher boiling point of iron compared to water is due to the strong metallic bonding between iron atoms, which requires more energy to break compared to the hydrogen bonds in water. This makes it harder for iron atoms to escape into the gas phase, resulting in a higher boiling point.
KCl is an ionic compound and glucose is a molecular compound. Ionic compounds have higher boiling points than molecular compounds.

The higher the pressure, the higher the boiling point. Boiling occurs when the atmospheric pressure equals the vapor pressure. So, at higher altitudes where the atmospheric pressure is lower, the vapor pressure is also lower which in turn creates a lower boiling point which causes foods to have to cook longer.
Ammonia: -33,34 0C Nitrogen trifluoride: -129 0C
A compound with a boiling point of 68°C is more likely to exist as individual molecules rather than a network structure. Network structures typically have higher boiling points due to the strong intermolecular forces holding the structure together. Lower boiling points are indicative of weaker intermolecular forces, suggesting that the compound is composed of individual molecules that can easily separate from each other at lower temperatures.
The separation method that includes evaporation is known as simple distillation. Simple distillation involves heating a liquid mixture to separate compounds based on differences in their boiling points. The higher boiling compound evaporates first, leaving behind the lower boiling compound.
Boiling-point elevation describes the phenomenon that the boiling point of a liquid (a solvent) will be higher when another compound is added, meaning that a solution has a higher boiling point than a pure solvent. This happens whenever a non-volatile solute, such as a salt, is added to a pure solvent, such as water. The boiling point can be measured accurately using an ebullioscope.
The boiling point of a compound is influenced by various factors, including intermolecular forces and molecular weight, and cannot be accurately predicted solely based on the boiling points of elements in it. The presence of functional groups and molecular structure also play a significant role in determining the boiling point of a compound.
These boiling points are:* CF4: -127,8 0C* CHF3: -82,1 0C
The structure of a compound will dictate what intermolecular forces hold the molecules together. The stronger these forces, the higher will be the 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.
Longer. The higher elevation causes the boiling point to decrease. Cook longer at higher elevations.
