Which type of molecule can ONLY involve London Forces as intermolecular attractions?
The only type of molecule that can only experience London forces (also known as Van der Waals interaction) is a non polar one. This can only occur in two situations:
- the molecule is composed completely of one nucleus, so that there is no electronegativity difference between nuclei. Examples of this include oxygen (O2) or diamond (a covalent lattice of carbon atoms).
- Differences of electronegativity are countered by equal differences in electronegativity, related by symmetry. Examples of this include carbon dioxide (CO2), carbon tetrachloride (CCl4).
What else can I help you with?
What are CH4's intermolecular forces?
CH4 (methane) is a nonpolar molecule, therefore its intermolecular forces are London dispersion forces. This is due to the temporary shifting of electron density within the molecule, creating weak attractions between neighboring molecules.
How does bonding effect the intermolecular forces?
Bonding affects intermolecular forces by influencing the strength of attractions between molecules. Covalent bonds within molecules contribute to intramolecular forces, while intermolecular forces, such as hydrogen bonding or van der Waals forces, occur between molecules. The type and strength of bonding within a molecule can impact the overall intermolecular forces affecting its physical properties.
Can viscosity be used to predict the strength of intermolecular attractions?
Yes, viscosity can be used to predict the strength of intermolecular attractions. Higher viscosity indicates stronger intermolecular forces because it requires more energy to overcome these forces, resulting in a thicker and more resistant fluid. Conversely, lower viscosity indicates weaker intermolecular attractions.
What bonds are a result of intermolecular forces?
Intermolecular forces are of the type(1) hydrogen bonds (2) dipole-dipole attractions (3) dispersion forces (van der Waals, etc.)
What is the Weakest kind of intermolecular force?
Dispersion forces (London dispersion forces) are generally the weakest type of intermolecular force. These forces are caused by temporary fluctuations in electron distribution around atoms or molecules, leading to weak attractions between them.
Why intramolecular forces stronger?
Intramolecuar forces are covalent bonds these involve the sharing of electrons. Intermolecular bonds are electrostatic in origin such as hydrogen bonds and London disprion forces which involve attractions between small charges.
What intermolecular forces are present in SiF4?
In SiF4, the intermolecular forces present are London dispersion forces. These forces arise due to temporary fluctuations in electron distribution within the molecule, leading to weak attractions between neighboring molecules.

What is a type of a intermolecular force?
London forces, dipole attractions and hydrogen bonding are some of the examples for intermolecular attractions in the order of increasing strength.
What is the intermolecular forces of CH3F?
The intermolecular forces of CH3F include dipole-dipole interactions and London dispersion forces. The molecule has a permanent dipole moment due to the difference in electronegativity between carbon, hydrogen, and fluorine atoms, leading to dipole-dipole attractions. Additionally, London dispersion forces, which result from temporary fluctuations in electron distribution, also contribute to the intermolecular forces in CH3F.
Can viscosity be used to predict the strength of intermolecular attractions?
Yes, viscosity can be used to predict the strength of intermolecular attractions. Higher viscosity indicates stronger intermolecular forces because it requires more energy to overcome these forces, resulting in a thicker and more resistant fluid. Conversely, lower viscosity indicates weaker intermolecular attractions.
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.
What is the intermolecular force of toluene?
The intermolecular force of toluene is primarily London dispersion forces, which are weak attractions between temporary dipoles in molecules. Toluene, being a nonpolar molecule, experiences these forces due to the momentary fluctuations in electron distribution.
How do the strengths of the intermolecular forces vary from CO2 to CS2 to CSe2?
Of CO2, CS2 and CSe2, CO2 is the smallest molecule whereas CSe2 is the largest molecule. The same pattern exists in the strength of the intermolecular forces. All three are linear, non polar molecules.
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 type of intermolecular forces operate in ICl gas?
dipole-dipole attractions
