REVIEW Questions and Answers
1.What are the 4 types of intermolecular forces listed from weakest to
strongest?
Answer London dispersion, dipole-dipole, hydrogen bonding, ion-
dipole
2.What effect does IMFs have on surface tension?
Answer surface tension increases as strength of IMF increase
3.What effect does IMFs have on viscosity?
Answer viscosity increases as strength of IMFs increase
4.What effect does IMFs have on boiling point?
Answer boiling point increases as strength of IMFs increase
