Force of attraction in chemistry refers to the attractive interactions between particles or molecules. It is responsible for holding atoms together, forming chemical bonds, and determining the physical and chemical properties of substances.
Detailed responses to the query
Force of attraction in chemistry refers to the powerful interactions between particles or molecules that play a central role in shaping the behavior and properties of substances. These attractive forces are crucial for holding atoms together in compounds and determining the physical and chemical characteristics of various substances.
A great quote from renowned chemist Linus Pauling encapsulates the significance of force of attraction in chemistry:
“Chemistry is the science of understanding the properties, composition, structure, and transformations of matter. The force of attraction lies at the heart of this scientific exploration, driving the formation of chemical bonds and enabling the vast array of substances we observe in the world.”
Here are some interesting facts about the force of attraction in chemistry:
-
Electromagnetic force: The force of attraction in chemistry, also known as the electromagnetic force, arises from the interaction between electric charges. Atoms and molecules have both positive and negative charges, which result in attractive forces between them.
-
Ionic bonds: The force of attraction plays a fundamental role in forming ionic bonds, where positively charged ions (cations) and negatively charged ions (anions) are held together by electrostatic forces. This results in the formation of compounds like sodium chloride (table salt).
-
Covalent bonds: Covalent bonds are formed when atoms share electrons, generating a force of attraction between the shared electrons and the nuclei of the atoms. This shared attraction holds the atoms together and gives rise to the vast majority of molecules in nature.
-
Intermolecular forces: These forces are the attractive interactions between molecules and are responsible for determining properties like boiling point, melting point, and solubility. Examples of intermolecular forces include London dispersion forces, dipole-dipole interactions, and hydrogen bonding.
-
Van der Waals forces: Van der Waals forces are a type of intermolecular force and encompass London dispersion forces and dipole-dipole interactions. These weak attractive forces exist between all atoms and molecules, regardless of their polarity. They contribute to the physical properties of substances like viscosity and surface tension.
Table on Types of Attraction Forces in Chemistry:
| Type of Force | Description |
|---|---|
| Ionic Bonds | Formed through the transfer of electrons between ions |
| Covalent Bonds | Arise when atoms share electrons |
| Hydrogen Bonding | Special type of dipole-dipole interaction |
| London Dispersion | Weak forces caused by temporary electron imbalances |
| Dipole-Dipole | Attractive forces between polar molecules |
| Van der Waals Forces | Collective term for London dispersion and dipole-dipole |
In conclusion, the force of attraction in chemistry is a crucial concept that underpins the formation of chemical bonds, determines the properties of substances, and drives the behavior of matter. Understanding these forces allows scientists to comprehend and manipulate the fascinating world of chemistry.

The force of attraction by which two atoms or two molecules combine to form a molecule or matter is termed as intermolecular force. It is basically attractive in nature. It acts between atom and ions also.
Forces of attraction are forces that act between neighboring particles (atoms, molecules or ions) due to the influence of their positive and negative charges. They are weak compared to the forces that keep a molecule together, such as covalent and ionic bonding. One example of forces of attraction is van der Waals forces, which are caused by temporary fluctuations of the electron clouds around the particles.
A visual response to the word “What is force of attraction in chemistry?”
This video explains the three types of intermolecular forces: permanent dipole-dipole forces, hydrogen bonds, and van der Waals forces. Permanent dipole-dipole forces exist between polar molecules, while hydrogen bonds form between a hydrogen atom and a highly electronegative atom on another molecule. Van der Waals forces are the weakest of the intermolecular forces and include London dispersion forces and instantaneous dipoles. The video emphasizes that intermolecular forces are weak compared to ionic or covalent bonds, and they occur in all molecules, whether polar or non-polar.
