15 Questions
What type of forces are responsible for the attraction between compound particles?
Intermolecular forces
Which type of forces are caused by the attraction of negative and positive charges?
Dipole-dipole attraction forces
In which order are the intermolecular forces listed according to their strength?
Dispersion forces, dipole-dipole attraction forces, hydrogen bonds
What is the collective name for dispersion and dipole-dipole attraction forces?
Van der Waal forces
What is a dipole in chemistry?
An atom or molecule with two oppositely charged points
What causes the distortion of the electron cloud in a non-polar atom when it is close to a dipole?
Attraction of the negative end of the dipole
In a system with non-polar atoms close together, what causes dipoles to be induced?
Polarization and being polarized
Why do substances with a higher boiling point have stronger intermolecular forces?
They have stronger attraction forces between particles
How are London dispersion forces influenced by molecular mass?
Higher mass leads to stronger forces
What factor influences the magnitude of London dispersion forces related to molecular shape?
Shape of the molecule
Why is the hydrogen fluoride molecule considered polar?
Fluorine has a slight negative charge and hydrogen has a slight positive charge.
What causes a nonpolar molecule to have dispersion forces?
Formation of instantaneous dipoles due to electron cloud motion.
What is the relationship between polarization power and polarizability in particles?
Particles with low polarization power have high polarizability.
What is responsible for London Dispersion Forces between nonpolar particles?
Induced dipole formation due to electron cloud distortion.
In nonpolar molecules like Argon, what leads to the temporary appearance of dipoles?
Concentration of electron cloud at one end at an instantaneous moment.
Learn about London dispersion forces, which are weak intermolecular forces that result from temporary shifts in electron density. Discover how these forces contribute to the attractions between molecules in chemistry.
