London Dispersion Forces

Which compound contains only London Dispersion Forces and Dipole-Dipole IMFs?

What is the weakest IMF?

• Hydrogen bonding

• Dipole dipole forces

• London Dispersion forces

• Covalent bonding

Answer explanation

London Dispersion forces are the weakest IMF among the options provided.

London dispersion forces happen between what types of molecules?

• Between non polar molecules

• Between polar molecules

Answer explanation

London dispersion forces occur between non polar molecules due to temporary fluctuations in electron distribution.

There are many types of intermolecular forces (IMF), and molecules go through them at different times.

However, which IMF would be the strongest between these molecules?

• London dispersion forces

• Dipole-dipole forces

• Hydrogen bonding

• Ionic forces

True or false: All molecules have London Dispersion forces between them. The strength of London dispersion force decreases as the weight of that molecule increase (molecular weight)

• True

• False

• Tralse

A kind of dispersion caused by polarization?

• London Dispersion Force

• Dipole - Diploe interaction

• Ion DIpole Forces

Which of the following molecules exhibits only London Dispersion Forces?

What is the primary factor that affects the strength of London Dispersion Forces?

True or False: London Dispersion Forces are present in all molecules, regardless of polarity.

• True

• False

Which of the following statements about London Dispersion Forces is true?

• They are stronger than hydrogen bonds.

• They occur only in polar molecules.

• They increase with increasing molecular size.

• They are the result of permanent dipoles.
