The molecular weights of the following five compounds are all between $100-102$ and will not be a factor in your answers to the questions. Do not look up data; answer the questions using basic principles of intermolecular force strength.

a$.$

b$.$

c$.HO-C{H}_{2}C{H}_{2}C{H}_{2}C{H}_{2}C{H}_{2}C{H}_3$

d$.C{H}_{3}C{H}_{2}C{H}_{2}C{H}_{2}C{H}_{2}C{H}_{2}C{H}_3$

$4.$ Identify the main $($strongest$)$ intermolecular force in a pure sample of each substance:

a$.$

b$.$

c$.$

d$.$

e$.$

$5.$ Which of two these molecules are most likely to be soluble in water? Explain using intermolecular forces.

$6.$ Which two of these molecules should have the highest $R_f$ values if the solvent toluene were used? $(C_7{H}_8).$ Explain using intermolecular forces.

$7.$ Arrange these molecules in expected order of increasing boiling point:
