How are melting point and boiling points affected by intermolecular forces?
The greater the intermolecular attraction, the higher the melting point and boiling point. Melting and boiling are both processes which have to overcome intermolecular attraction.
How are intermolecular forces related to the boiling and melting pts of molecules?
The stronger the intermolecular forces, the higher the melting point and boiling point. The weaker the intermolecular forces, the lower the melting and boiling points are.
Why are the melting and boiling points of covalent compounds are usually low than those in ionic compounds?
Melting and boiling points are determined by the strength of the intermolecular forces present in the compound. The stronger the intermolecular forces, the higher the melting and boiling points. There are four types of intermolecular forces, from lowest strength to highest: London dispersion forces, dipole-dipole, hydrogen bonding, and ion-dipole. Ionic compounds will have ion-dipole intermolecular forces. Because this is the strongest intermolecular force, ionic compounds will also have the highest melting and boiling points.
How do intermolecular forces affect boiling point of a liquid?
Low intermolecular forces, low boiling point.
What is the relationship between the strength of intermolecular forces and boiling point?
as the intermolecular forces increses the boiling point is increses

How are intermolecular forces related to the boiling and melting pts of molecules?
The stronger the intermolecular forces, the higher the melting point and boiling point. The weaker the intermolecular forces, the lower the melting and boiling points are.
Does intermolecular forces have a boiling or melting point?
An intermolecular force has both a boiling point and melting point

How does intermolecular forces affect boiling point?
The greater the intermolecular forces in a liquid, the higher is its boiling point.
How do intermolecular forces affect boiling point of a liquid?
Low intermolecular forces, low boiling point.
What is the relationship between the strength of intermolecular forces and boiling point?
as the intermolecular forces increses the boiling point is increses
What properties are affected by the strength of the intermolecular forces?
The physical properties of melting point, boiling point, vapor pressure, evaporation, viscosity, surface tension, and solubility are related to the strength of attractive forces between molecules.
How is high melting and boiling points related to the structure of the compounds?
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.
Why do dipole forces have an impact on the melting and boiling points of substances?
Dipoles are a form of intermolecular force which holds molecules together. The greater the intermolecular force, usually the greater the boiling point, for example.
What is the relationship between the strength of the intermolecular forces and boiling point?
Boiling can only occur when the kinetic energy of heat overcomes the intermolecular forces holding a liquid together, so the greater the intermolecular forces, the higher the boiling point.
What can infer about the attraction between particles in a substance with a low melting point?
The stronger the intermolecular forces, the higher the boiling point, because more kinetic energy is needed to break these intermolecular forces apart.
