It's a type of inter-molecular force. They're called London Dispersion Forces (one of a group of different intermolecular forces known generically as Van der Waals Forces). These forces are weak and short-lived, and created by the interaction of instantaneous dipoles The larger the molecule, the stronger the London Forces because there are more electrons to create an attraction.
What else can I help you with?
Are all intermolecular forces similar?
They vary depending on the molecules under consideration. They are all electrostatic in nature deriving from the interaction of permanent or instantaneous dipoles. They are lumped together as Van der Waals forces but can be considered to be of 3 types:-Keesom forces permanent dipole dipole interactionsDebye forces; permanent dipole interaction with induced dipole,London dispersion forces ; interaction between two instantaneous dipoles.
What is the nature of attractive force among molecules in liquid bromine?
The attractive force among molecules in liquid bromine is primarily due to London dispersion forces, which are weak intermolecular forces that result from temporary fluctuations in electron distribution within molecules. These forces are responsible for holding the molecules together in the liquid phase.
Is the bonds that cause gaseous Cl2 to become liquid when cool intramolecular or intermolecular?
Intermolecular because intermolecular forces occur between molecules, not within the same molecule. Specifically the forces are London dispersion forces, due to the interaction of instantaneous dipoles.
Why is ph3 Dispersion and Dipole-Dipole?
PH3 has a dipole moment , of 0.58 D. Therefore there will be dipole dipole interactions. All molecules experience London dispersion forces as these are caused by the interaction of instantaneous dipoles due to the movement of electrons within the molecules.
What type of interaction would you expect between r group in the tertiary structure OS protein ch2c000 and ch2ch2ch2ch2nh3?
I would expect a Van der Waals interaction between the R group in the tertiary structure of the protein and the CH2CH2CH2CH2NH3 group. This interaction occurs due to the transient dipoles created by the movement of electrons in the molecules. It helps stabilize the structure of the protein by providing additional attractive forces between the two groups.
Are the attractive forces between polyethylene chains due to permanent dipoles or induced dipoles?
The attractive forces between chains are due to instantaneous induced dipoles, London dispersion forces,( not induced diipoles due to permananent dipoles). Polyethylene chains are long and the number of electrons is large- the intermolecular attraction will be significant.
London dispersion forces produce two kinds of dipoles which comes first?
the instantaneous dipole
How are the London forces between molecules produced?
London forces, also known as dispersion forces, arise from the temporary fluctuations in electron distribution within molecules, leading to the formation of instantaneous dipoles. These dipoles can induce corresponding dipoles in neighboring molecules, resulting in a weak attractive force between them. The strength of London forces increases with the number of electrons and the size of the molecules, making larger and more polarizable molecules exhibit stronger dispersion interactions. Overall, these forces are a fundamental type of van der Waals forces that contribute to the physical properties of substances.

An intermolecular force is also called an induced force?
An intermolecular force is not typically referred to as an "induced force"; rather, it generally includes forces such as hydrogen bonds, dipole-dipole interactions, and London dispersion forces. Induced forces specifically refer to the temporary attractions that occur when electrons in a molecule are redistributed due to the influence of nearby charges or dipoles, leading to instantaneous dipoles. While induced forces are a type of intermolecular interaction, they are not synonymous with the broader category of intermolecular forces.
What is the every day importance of induced dipoles?
Induced dipoles are important in everyday life because they play a role in various phenomena. For example, they are responsible for the attractive forces between molecules in liquids and solids, which determine the physical properties of substances such as boiling point and viscosity. Induced dipoles also contribute to the formation of hydrogen bonds, which are crucial for the structure and function of biological molecules like DNA and proteins. Additionally, they are involved in the interaction between materials in applications such as adhesion and chromatography.

Do London dispersion forces exist between polar molecules and result from temporary dipoles?
London dispersion forces derive from the interraction of instantaneous induced dipoles - the inetraction of polar molecules (having a permanent dipole )is called a Keesom force- the force between a permanent polar molecule and an induced dipole in another molecule is called a debye force--
