Yes, van der Waals forces are generally weaker than chemical bonds. Van der Waals forces are intermolecular forces that result from temporary fluctuations in electron distribution, while chemical bonds involve the sharing or transfer of electrons between atoms to form more stable structures.
Yes, benzene dimers can interact via Van der Waals interactions due to the presence of temporary dipoles. These interactions are weak compared to covalent bonds but can contribute to the overall stability of the dimer.
yes
Helium has the weakest Van der Waals forces among these noble gases. This is because helium is a monatomic gas, meaning it has only one atom per molecule, resulting in weaker Van der Waals interactions compared to larger noble gases like argon, krypton, and neon.
No, HE2 is not a van der Waals molecule as Helium typically exists as a monatomic gas and does not readily form stable compounds or molecules with other elements.
