Which intermolecular force requires hydrogen and one of the following: nitrogen, oxygen, fluorine?

• Dipole-dipole

• Hydrogen bonding

• London dispersion forces

Which type of intermolecular force does this molecular drawing best represent?

• dipole-dipole forces

• hydrogen bonding

• London dispersion forces

All molecules have London forces between them, but dipole-dipole and hydrogen bonding are so much stronger that when they are present we can ignore London forces.  Which of these has ONLY London forces?

• I₂

• NH₃

• OCl₂

• SH₂

Which substance has the weakest intermolecular forces?

What is the basis of hydrogen bond?

• Attraction forces between hydrogen atom bonded with another hydrogen atom

• Attraction forces between hydrogen atom bonded with a high electronegativity atom (F, O, N)

• Attraction forces between hydrogen atom bonded with a high electronegativity atom (F, O, N) with atom (F, O, N) of another molecule

• Attraction forces between hydrogen atom with another hydrogen atom of another molecule

Which intermolecular force do all molecules have?
