Answer is: 1. decane, c10h22

This pair will most likely form a homogeneous solution because they are both nonpolar substances and "like dissolves like".

Other pairs will not form homogeneous solution because polar (methanol, sugar) or ionic (h ydrofluoric acid) substances have low solubility in nopolar (benzene) substances.
