Intermolecular Forces

Evaporation and Intermolecular(a) Attractions In this experiment, Temperature Probes are placed in various liquids. Evaporation occurs when the probe is removed from the liquids container. This evaporation is an endothermic process that results in a temperature decrease. The arrangement of a temperature decrease is, like viscosity and boiling temperature, retrieve to the strength of intermolecular forces of attraction. In this experiment, you volition study temperature changes ca delectationd by the evaporation of some(prenominal) liquids and relate the temperature changes to the strength of intermolecular forces of attraction. You squeeze back up stakes use the results to predict, and then measure, the temperature change for several(prenominal)(prenominal) other liquids. You will encounter 2 types of organic compounds in this experimentalkanes and alcohols. The both alkanes are pentane, C5H12, and hexane, C6H14. In addition to blow and hydrogen atoms, alcohols exce ssively contain the -OH functional group. Methanol, CH3OH, and ethanol, C2H5OH, are both of the alcohols that we will use in this experiment. You will examine the molecular structure of alkanes and alcohols for the front line and relative strength of two intermolecular forceshydrogen stick and dispersion forces. OBJECTIVES IN THIS EXPERIMENT, YOU pull up stakes * Study temperature changes caused by the evaporation of several liquids. * Relate the temperature changes to the strength of intermolecular forces of attraction.
