You separate a mixture that contains N2, HF, and CH3 using paper chromatography. The picture on the right shows your results. Which molecule is which? A
N2 is yellow, CH3 is red, and HF is blue. I can tell because HF would form hydrogen bonds, causing it to have a weak attraction to the polar paper. N2 would form van der Waal forces. It would have strong partial charges to attract to the paper.

B
N2 is blue, CH3 is red, and HF is yellow. I can tell because HF would form hydrogen bonds, allowing it to attract the most strongly to the polar paper. N2 would form van der Waal forces. It would not have strong partial charges to attract to the paper.

C
CH3 is yellow, HF is red, and N2 is blue. I can tell because CH3 is polar, and would form a strong intermolecular force with the polar paper. N2 is nonpolar, and would not form a strong attraction with the polar paper.
