Chemistry - CHEMICAL BONDING Question with Solution | TestHub
The sum of three attractive forces—Keesom forces, Debye forces, and London forces—is called the van der Waals forces. Thus, the total attractive interaction energy is given by:
: It arises due to the proper orientation of the permanent dipole moments of the molecules.
: It arises due to the interaction of an induced dipole moment of one molecule with the permanent dipole moment of the polarizing molecule.
: It arises due to the interaction between instantaneously developed dipole moments through the synchronization of charge cloud imbalance.
Which of the following can show maximum interaction with ?
Options:
Answer:
Solution:
The interaction between noble gases and H₂O is primarily due to London dispersion forces and induced dipole interactions. Larger noble gas atoms (like Xe) are more polarizable, meaning their electron clouds can be more easily distorted to form temporary dipoles. This leads to stronger induced dipole interactions with the polar H₂O molecule, resulting in maximum interaction.
Therefore, Xe can show maximum interaction with H₂O.
