Student understanding of intermolecular forces and their impact on the properties of substances has always been a bit tricky for me in the past. . Based on this, students now have evidence to support the idea that the -OH group must be playing some kind of significant role and their original claim that longer alkanes result in greater attraction is now in question and must be modified in some way. Surface tension is given by the equation S = (hga/2) where S is the surface tension, (or rho) is the density of the liquid you are measuring, h is the height the liquid rises in the tube, g is the acceleration due to gravity acting on the liquid (9.8 m/s2) and a is the radius of the capillary tube. The last part of this activity introduces students to the concept of hydrogen bonding by looking at how water molecules interact with one another (Figure 7). Pretty cool, right?
