24angle = 120
=> Larger bond angle
angle = <109.5
5. (5 points) When a thin glass tube is put into water, the water rises 1.4 cm. When the
same tube is put into hexane, the hexane rises only 0.4 cm. Explain the difference.
Water can generate strong adhesive interactions with the glass (due to the
dipoles at the surface of the glass), but hexane is nonpolar and cannot interact
strongly with the glass surface.
