The preferred phase of a substance at a given set of conditions is a balance between the energy of the particles and intermolecular forces (or intermolecular interactions) between the particles. If the forces between particles are strong enough, the substance is a liquid or, if stronger, a solid.
What phase has the strongest intermolecular forces?
Due to the solid’s low kinetic energy, particles have no “time” to move around, the particles have more “time” to be attracted. Therefore, solids have the strongest intramolecular forces (because they have the strongest attraction).
Which phase of IMF is weakest?
- Oil- Only London Dispersion Forces (the weakest intermolecular force)
- Water- London Dispersion, Dipole-Dipole, and Hydrogen Bonding.
Which state has the strongest intermolecular forces?
The solid-state has the strongest intermolecular forces of attraction and so their molecules are close to each other.
What are the strongest to weakest intermolecular forces?
In order from strongest to weakest, the intermolecular forces given in the answer choices are: ion-dipole, hydrogen bonding, dipole-dipole, and Van der Waals forces.
Which liquid has the strongest intermolecular forces?
Water has the strongest intermolecular forces (hydrogen bonds) of all the substances used.
Why hydrogen bonding is the strongest intermolecular force?
Hydrogen bonds are strong intermolecular forces created when a hydrogen atom bonded to an electronegative atom approaches a nearby electronegative atom. Greater electronegativity of the hydrogen bond acceptor will lead to an increase in hydrogen-bond strength.
Which van der Waals force is the weakest?
Dispersion forces are also considered a type of van der Waals force and are the weakest of all intermolecular forces. They are often called London forces after Fritz London (1900-1954), who first proposed their existence in 1930.
Which attractive force is the weakest?
Dispersion forces are the weakest intermolecular force (one hundredth-one thousandth the strength of a covalent bond), hydrogen bonds are the strongest intermolecular force (about one-tenth the strength of a covalent bond).
What are attractive forces?
attractive force – the force by which one object attracts another. attraction. affinity – (immunology) the attraction between an antigen and an antibody. bond, chemical bond – an electrical force linking atoms.
Which state of matter has the least intermolecular forces?
The state of matter with the least intermolecular forces of attraction is the gaseous state. The molecules of gases are loosely bounded and are far apart from each other.
Which hydrogen bonding is the strongest?
The strength of hydrogen bond depends upon the coulumbic interaction between the electronegativity of the attached atom and hydrogen. Fluorine is the most electronegative element. F−H−−−F bond will be strongest H bond.
Which state of matter has the biggest intermolecular space?
Intermolecular space is the space between two molecule or atom. In solids it is very little, in liquids is more the solids but less than liquids and in gases its the maximum.
