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.
What is aligned dipoles?
Aligned dipoles refer to a configuration in which electric or magnetic dipoles are arranged in a specific orientation. This alignment can occur naturally in certain materials or be induced through external fields. The resulting collective orientation of the dipoles can lead to unique electromagnetic properties.
What is the intermolecular force of P4?
The primary intermolecular force present in tetraphosphorus (P4) is London dispersion forces, which are a type of van der Waals force. These forces arise due to temporary fluctuations in electron density that create instantaneous dipoles, leading to induced dipoles in neighboring molecules. While P4 is nonpolar and has no significant dipole-dipole interactions or hydrogen bonding, London dispersion forces are sufficient to account for its physical properties, such as its relatively low melting and boiling points compared to polar substances.
What type of intermolecular force is present in c6H12?
London dispersion forces (instantaneous induced dipole-dipole interactions.)
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.
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.
Which substance f2 or cl2 has the stronger intermolecular forces?
Cl2 has a stronger intermolecular forces, London dispersion forces, as there are more electrons in Cl2 than in F2 It is the electrons that cause the instantaneous dipole-induced dipole interactions, more electrons = more dipoles and more easily induced dipoles = more london forces.
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.
Are induced dipoles permanent?
Induced dipoles are temporary and not permanent. They are created in nonpolar molecules when they are exposed to an electric field, causing the distribution of electrons to shift temporarily, resulting in the formation of a dipole moment. Once the electric field is removed, the induced dipoles disappear.
What is aligned dipoles?
Aligned dipoles refer to a configuration in which electric or magnetic dipoles are arranged in a specific orientation. This alignment can occur naturally in certain materials or be induced through external fields. The resulting collective orientation of the dipoles can lead to unique electromagnetic properties.
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 type of intermolecular force present in Br2?
The type of intermolecular force present in Br2 is London dispersion forces. These forces are the weakest of the intermolecular forces and result from temporary fluctuations in electron distribution around the molecule, leading to a temporary dipole moment.
What type of intermolecular force is present in c6H12?
London dispersion forces (instantaneous induced dipole-dipole interactions.)
What is the intermolecular force of octasulfur?
The intermolecular force of octasulfur (S8) is dispersion forces. Sulfur molecules are nonpolar, so the only force of attraction between them is due to temporary dipoles induced by momentary fluctuations in electron distribution.
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 intermolecular forces of BeI2?
BeI2 is a solid it melts at 480 0 or higher according to another source. It is a covalent solid made up of long chains of four coordinate beryllium atoms. In the vapour and probably in the liquid it is dimeric. the forces will be dispersion forces, also known as London forces and induced dipole forces or instantaneous dipole-induced dipole forces.
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--
