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.
Why vanderwall forces are weak forces?
The question should be, why is there a force at all! In the case of van der Waals forces, a.k.a. "induced dipole - induced dipole", there is no charge separation, or charge, present to begin with; only temporary dipoles caused by random movement of particles.
The weak intermolecular forces resulting from instantaneous and induced dipoles are called?
London dispersion forces.
What type of forces exist between I2 molecules?
The forces between I2 molecules are London dispersion forces, which are weak intermolecular forces resulting from temporary dipoles induced in the molecules. These forces occur due to the movement of electrons around the nonpolar I2 molecules, leading to transient uneven distributions of charge.
What are the main interaction between molecule of CH4?
The main interaction between CH4 molecules are London dispersion forces, which result from temporary dipoles induced in the molecules. These forces are relatively weak compared to other intermolecular forces like hydrogen bonding.
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--

What are Van der Waala forces?
Van der Waals forces are weak, short-range attractive forces between molecules. They can arise from dipole-dipole interactions, induced dipoles, or interactions between temporary dipoles. These forces play a role in determining the physical properties of substances such as melting point, boiling point, and solubility.
The weak intermolecular forces resulting from instantaneous and induced dipoles are called?
London dispersion forces.
What type of intermolecular force is common to xenon and methanol?
The common intermolecular force between xenon and methanol is London dispersion forces. Xenon is a noble gas with temporary fluctuations in electron distribution, while methanol has a polar OH group that can induce temporary dipoles in nearby xenon molecules, leading to weak attractive forces.
How do van derwaals forces arise?
Van der Waals forces arise due to temporary fluctuations in electron density within atoms or molecules, creating temporary dipole moments. These induced dipoles then attract each other, resulting in the weak van der Waals forces.
What type of forces exist between I2 molecules?
The forces between I2 molecules are London dispersion forces, which are weak intermolecular forces resulting from temporary dipoles induced in the molecules. These forces occur due to the movement of electrons around the nonpolar I2 molecules, leading to transient uneven distributions of charge.

Which intermolecular force is predominant in non-polar molecule?
The predominant intermolecular force in non-polar molecules is London dispersion forces, also known as Van der Waals forces. These forces are due to temporary fluctuations in electron distribution within the molecule, creating temporary dipoles that attract each other.
What is Intermolecular force of Silicon Tetrabromide?
Silicon tetrabromide exhibits van der Waals forces as its primary intermolecular force. These forces arise from temporary dipoles induced by the unequal distribution of electrons in the molecule, resulting in weak attractions between silicon tetrabromide molecules.
What types of intermolecular force is present in alkanes?
Alkanes only interact with each other via London Dispersion, also known as induced-dipole induced-dipole, forces. Since alkanes do not contain any atoms other than Carbon and Hydrogen, they are non-polar. However, as the electrons move freely about their orbital, some temporary polarity is formed. These induced dipoles can interact with each other to create intermolecular bonding between non-polar alkanes. The more surface area the alkane has, the stronger these forces will be.
