Why is the boiling point of butanone higher than pentane?
Butane is a smaller molecule, so the London Dispersion forces between molecules of butane hold the molecule together better than the London Dispersion forces of a hexane molecule. In short, it requires more energy to separate butane molecules from each other than hexane molecules.
What type of forces hold subatomic forces together?
between molecules the forces are called intermolecular forces, and between the atoms in a molecule they are called inramolecular forces
In steam are the forces between molecules the same as the forces between the molecules in water?
No, they are not. The forces between molecules in steam are not as strong as those present in liquid water.
What holds molecules of compounds together?
Within the molecule, covalent bonds hold them together. Between the molecules there can be several different forces. There are dipole-dipole attractions, hydrogen bonds and van der Waals forces. Which of them apply in a particular substance depends on the structure of the molecules.
How are intermolecular forces different from forces that bind atoms together into molecules?
1. Intermolecular forces are the forces between molecules, while chemical bonds are the forces within molecules. 2. Chemical bonds combine atoms into molecules, thus forming chemical substances, while intermolecular forces bind molecules together. 3. Chemical bonding involves the sharing or transferring of electrons, while intermolecular forces do not change the electron stucture of atoms. 4. Intermolecular forces hold objects together, while chemical bonds hold molecules together.

Solid state
How do the molecules of a solid differ from the molecules in a gas?
In solid, the molecules r tightly packed by intermolecular forces, but in gas these forces r very loose.

between molecules the forces are called intermolecular forces, and between the atoms in a molecule they are called inramolecular forces
Why is it difficult to change the shape of a solid?
It is difficult to change the shape of a solid as the molecules of it are tightly packed together and have strong intermolecular forces. As they have strong forces of attraction the molecules cannot move away from their position and hence it is difficult change their shape.
In steam are the forces between molecules the same as the forces between the molecules in water?
No, they are not. The forces between molecules in steam are not as strong as those present in liquid water.
What is the predominant force between IBr molecules in liquid IBr?
The predominant force between IBr molecules in liquid IBr is Van der Waals forces, specifically dipole-dipole interactions and London dispersion forces. These forces are responsible for holding the IBr molecules together in the liquid state.
What holds molecules of compounds together?
Within the molecule, covalent bonds hold them together. Between the molecules there can be several different forces. There are dipole-dipole attractions, hydrogen bonds and van der Waals forces. Which of them apply in a particular substance depends on the structure of the molecules.
What do dipole dipole forces do?
Hold polar molecules together
How do intermolecular forces determine a substance's state?
If the intermolecular forces are great enough they can hold the molecules together as a liquid. If they are even stronger they will hold the molecules together as a solid. Water has nearly the same mass as methane and ammonia molecules, but the greater molecular forces between water molecules causes the water to be liquid at room temperature, while ammonia and methane, with weaker intermolecular forces, are gases at room temperature.
What happens to the particles in a solid when it dissolved?
The particles in the solid (solute) break apart and form links with the particles in the liquid (solvent). There are strong forces of attraction between the molecules and particles inside the solute. These forces keep the particles together and make the solute a solid because they attract the solute particles tightly together. There are also strong forces of attraction between the molecules and particles inside the solvent. These forces keep the particles together and make the solvent a liquid because they attract the solvent particles slightly together. There is also an attractive force between the solute and solvent particles. To break these forces and from a bond between the solute and solvent particles energy is needed. This energy is gained from heat (the process of dissolving is speeded up through heat.) In conclusion, the particles in a solute break apart of their attractive forces and form bonds with the solvent particles through the attraction between the solute and solvent particles and through the energy gained by heat.
