(a) Calculate the surface areas of the isomers 2,2-dimethylpropane and pentane. Assume that 2,2-dimethylpropane is spherical with a radius of 254 pm and that pentane can be approximated by a rectangular prism with dimensions 295 pm * 692 pm * 766 pm.

(b) Which has the larger surface area?

(c) Which do you expect to have the higher boiling point?
