Dipole-induced dipole forces of attraction exist between water and gasoline, and yet, these two substances do not mix because water has such a strong attraction for itself. Which of the following compounds might best help to make these two substances mix into a single liquid phase?
A. the molecule in the middle because when the salts mix into the water, it will help separate the water and decrease the attraction for itself B. the molecule on the far left because the O-H bond is polar, and the carbon and hydrogen bonds are nonpolar C. The molecule on the right will form attractions with the polar ends of the water, allowing the gasoline a chance to mix with the water. D. All of these molecules would be equally effective at increasing the mixing of gasoline and water.
