The boiling point is highly dependent on the intermolecular forces of the compound. Compounds with stronger intermolecular forces, greater mass, and fewer branches will have a higher boiling point.
What makes compounds have higher boiling points?
Because larger molecules have more electrons and nuclei that produce van der Waals attraction, they usually have a higher boiling point than similar compounds composed of smaller molecules.
How do you tell which solution will have the highest boiling point?
Multiply the original molality (m) of the solution by the number of particles formed when the solution dissolves. This gives the total concentration of dissolved particles. These values are then compared. The higher the total concentration, the higher the boiling point and the lower the freezing point.
Which compounds should have the highest boiling point?
Propionamide has the strongest intermolecular forces, but should have the highest boiling point.
What factors influence boiling point?
The boiling point of a liquid depends on temperature, atmospheric pressure, and vapor pressure of the liquid. Boiling begins when the atmospheric pressure equals the vapor pressure of the liquid.
What determines boiling point of an element?
Bright elements such as hydrogen and helium tend to have very low boiling points, while elements with higher atomic masses boil higher. Atomic mass affects the forces between atoms and determines the boiling point.
