Main Difference – Intermolecular vs Intramolecular Forces

Intermolecular and intramolecular forces are the two types of forces that host individual molecules and atoms together. This forces control the movement of molecules and atoms. Both types of forces determine the chemical and physical attributes of substances. The main difference in between intermolecular and intramolecular forces is the intermolecular forces exist in between the molecules themselves, vice versa, intramolecular pressures exist between atoms in ~ a molecule. In addition, there are many much more differences between these forces.

What room Intermolecular Forces

Intermolecular forces are forces that tie individual molecules in a substance as result of their positive and an adverse charges. Intermolecular forces are attractive forces, however not chemical bonds. Thus, intermolecular forces are lot weaker than intramolecular forces. These pressures determine the physical features of a substance. Among their most important physical qualities is the capacity to recognize the state the a problem – whether it is solid, fluid or gas. These pressures are responsible for the random activity of gasses and the visibility of liquids and also solids as they host liquid and also solid molecule together. Hence, intermolecular forces determine the melting and boiling suggest of the matter. Melt or boiling allude is proportional to the stamin of intermolecular forces. I.e., the higher the melting or boiling point, the more powerful the intermolecular forces. In ~ a given temperature, the strengths of intermolecular pressures of gas, liquid and solid are as follows.

Gas electrons and also nuclei in the molecules. Among the three types, hydrogen bonds space the strongest kind of intermolecular bonds. Water molecules are organized by hydrogen bonds due to the presence of partial charges at particular locations on the molecules.


What are Intramolecular Forces

Forces that hold atoms in a molecule are referred to as intramolecular forces. These forces are responsible because that the formation of chemical bonds. Thus, intramolecular forces are lot stronger than intermolecular forces. Intramolecular interactions happen when two atoms share electrons or donate/gain electron to/from one more atom. Once electrons room shared in between two atoms, the link is dubbed a covalent bond. When one atom gives/ get electron, the shortcut is referred to as an ionic bond. Intramolecular forces determine chemistry parameters that a substance. Steel bonds are likewise classified together a kind of intramolecular force.


Difference in between Intermolecular and Intramolecular Forces


Intermolecular forces are the pressures that hold molecules in a substance.

Intramolecular forces are the pressures that hold atoms in a molecule.


Intermolecular forces space weaker than intramolecular forces.

Intramolecular forces are stronger 보다 intermolecular forces.

Determination of nature

Intermolecular forces identify the state of issue (solid/liquid/gas) and also their physical properties such as melting/ boiling allude etc.

Intramolecular forces recognize chemical actions of a substance.

Nature that Forces

Intermolecular forces are attractive forces.

Intramolecular forces room chemical bonds.


Intermolecular forces space categorized into dipole-dipole forces, London dispersion forces and also hydrogen bonding forces.

Intramolecular forces room categorized into covalent, ionic and also metal bonds.
