Pentane is a C5 hydrocarbon, gasoline contains mostly C8 hydrocarbons, and fuel oil contains hydrocarbons in the C12 range. List these three hydrocarbons in order of increasing viscosity, and explain what molecular feature accounts for the variation.

Select the correct option amongst the words in parenthesis

The viscosities of a set of similar substances (increases, decreases) with increasing chain length, because of (increased, decreased) dispersion forces and  (increased, decreased)  "tangling". Thus, the order of increasing viscosity is (fuel oil, pentane, gasoline) < (fuel oil, pentane, gasoline) < (fuel oil, pentane, gasoline)
