Effect of Intermolecular Forces on Viscosity• • – Our goal for this experiment is the effect of intermolecular forces on viscosity. What molecule? What IMF will they show? – We did measure the mixtures, are cyclohexane-cyclohexanone, cyclohexanecyclohexanol, and cyclohexanone- cyclohexanol. • Viscometry is a useful method for determining the viscosity – We used a Cannon-Fenske viscometer to measure the viscosity https://www.bing.com/search?q=%EF%82%A7%20https%3A%2F%2Fcannoninstrument.com%2Fma nual-glassviscometers%2Fcannon-fenske-routineviscometer.html&pc=0ADV&ptag=C24N1809AE19AA1A068&form=CONBNT&conlogo=CT32101 27 Experimental section: […]
