For each of the solutions from above order the following in increasing polarity (from lowest to highest): solvent, more polar molecule, less polar molecule, silica gel. If the difference cannot be determined, indicate this by entering N/D. Note you might have to use a bit of logic and consider the properties of each. Useful information is found in the lab manual and student guide.

Solvent, less polar molecule, more polar molecule, silica gel

Explanation:

Solvent has lowest polarity but less polar molecule has more polarity than solvent. The more polar molecule has higher polarity value whereas silica gel has the highest polarity. The polarity of compounds is due to the difference of electronegativity values of the elements that bonded with each other. The difference of electronegativity value is high between silicon and oxygen is responsible for high polarity of silica gel.

i think the answer is terrae but not 100 percent sure. ▓▬▬ §
