What causes the attractive force?
Polar molecules align so that the positive end of one molecule interacts with the negative end of another molecule. Unlike covalent bonds between atoms within a molecule ( intramolecular bonding), dipole-dipole interactions create attractions between molecules of a substance ( intermolecular attractions).
What do the forces of attraction depend on?
There are three types of attractive forces. The gravitational attraction depends on masses, electrical attraction depends on opposite charges, and magnetic attraction depends on currents going in the same direction. The gravitational force is the only force that is purely attractive.
What causes the attractive forces between particles in matter?
The particles that make up some matter are close together and vibrate back and forth. … If the motion of particles slows the particles move closer together. This is because the attraction between them pulls them toward each other. Strong attractive forces hold particles close together.
What is attractive force?
Definitions of attractive force. the force by which one object attracts another. synonyms: attraction. Antonyms: repulsion, repulsive force. the force by which bodies repel one another.
Which has more intermolecular force of attraction?
Dipole-dipole interactions are the strongest intermolecular force of attraction.
What factors affect intermolecular forces?
– temperature – pressure – The kinetic energy of the particles. – The strength of the attractions between the particles. Molecules/atoms can stick to each other. But much more weakly than a bond.
What is vanderwall force of attraction?
van der Waals forces, relatively weak electric forces that attract neutral molecules to one another in gases, in liquefied and solidified gases, and in almost all organic liquids and solids. … The tendency of such permanent dipoles to align with each other results in a net attractive force.
What attractive force holds atoms together?
Chemical bonds are the forces of attraction that tie atoms together. Bonds are formed when valence electrons, the electrons in the outermost electronic “shell” of an atom, interact. The nature of the interaction between the atoms depends on their relative electronegativity.
What are the different types of attractive forces?
Attractive intermolecular forces are categorized into the following types:
- Hydrogen bonding.
- Ion–induced dipole forces.
- Ion–dipole forces.
- van der Waals forces – Keesom force, Debye force, and London dispersion force.
How intermolecular forces of attraction affect viscosity?
Intermolecular forces present in a liquid is a factor which affects its viscosity. Higher the intermolecular forces, higher will be the viscosity. When there is a strong intermolecular force, the molecules of the liquids are strongly bonded to each other. This induces a resistance to move.
