Which substances exhibit only London forces?

H2O and HCl all contain polar covalent bonds. Hydrogen is bonded to a highly electronegative atom hence these substances exhibit hydrogen bond. Cl2 is nonpolar, same applies to He. Cl2 is a formed by a homonuclear covalent bond hence both He and Cl2 contain only London forces.

Which compounds exhibit only London dispersion intermolecular forces?

Intermolecular forces are attractive forces between molecules or between molecules and ions. These forces are weaker compared to bonding forces. London dispersion forces are present in all molecules. For nonpolar molecules and noble gas atoms, only London dispersion forces exist.

Which of the following molecules is only London dispersion forces?

These London dispersion forces are often found in the halogens (e.g., F2 and I2), the noble gases (e.g., Ne and Ar), and in other non-polar molecules, such as carbon dioxide and methane. London dispersion forces are part of the van der Waals forces, or weak intermolecular attractions.

Does BCl3 exhibit only London dispersion forces?

Intermolecular force is the force between molecules it includes the forces of attraction and repulsion. however the intermolecular forces are weaker than intramolecular force. BCl3 has London dispersion force.

What causes London dispersion forces?

The London dispersion force is the weakest intermolecular force. The London dispersion force is a temporary attractive force that results when the electrons in two adjacent atoms occupy positions that make the atoms form temporary dipoles. This force is sometimes called an induced dipole-induced dipole attraction.

What do intramolecular forces determine?

Intermolecular forces determine bulk properties, such as the melting points of solids and the boiling points of liquids. Liquids boil when the molecules have enough thermal energy to overcome the intermolecular attractive forces that hold them together, thereby forming bubbles of vapor within the liquid.
