Question

Asphalt is a mixture of high molecular weight hydrocarbons. Which solvent would be best for removing asphalt from a newly paved road off the bottom of a pair of shoes?

a. Water
b. Octane
c. Menthanol, CH₃OH
d. NaCl

Answer 1

Octane is the best solvent for removing asphalt from a pair of shoes.

Step-by-step explanation:

Asphalt is a mixture of high molecular weight hydrocarbons and is typically insoluble in polar solvents like water. The best solvent for removing asphalt from a pair of shoes would be a nonpolar solvent, such as octane. Octane is a hydrocarbon and has similar properties to asphalt, so it would be effective in dissolving and removing the asphalt from the shoes.
