a. What is the relationship between surface area and LDF (London Dispersion Forces)? Explain why.

b. Two of the liquids, n-pentane and 1-butanol, had nearly the same molar masses, but significantly different T values. Explain the difference in T values of these substances, based on their intermolecular forces. Be sure to compare and contrast: what is the same? Different?

c. Using the T data, list the alcohols in order of increasing intermolecular forces of attraction. (Be sure to give the T values with each compound.) Explain the order of the list by comparing and contrasting the intermolecular forces for the alcohols: what is the same? Different?
