IMF and Polarity - Haris and Trevor

What is an Intermolecular force?

• the ability to form instantaneous dipoles

• something that holds atoms together within a molecule

• attractive forces between molecules

What does the electronegativity of an atom create?

• a dipole or polar molecule

• hydrogen bond

• a compound

What is the strongest IMF(out of these)?

• dipole- induced dipole

• hydrogen bond

• dipole- dipole

What is the least strongest IMF(out of all)?

• dipole- dipole

• dipole- induced dipole

• London dispersion force

• hydrogen bond

What are London Dispersion Forces?

• attraction between one polar and one nonpolar molecule

• attraction between two nonpolar molecules

• attraction between 2 polar molecules
