PURPOSE (4 pts)
The purpose is to measure the enthalpies of vaporazation of pentane, diethyl ether, butanone, and 2-butanol.
For each of these molecules, a portion of the enthalpy of vaporization is due to dispersion forces (all molecules have
dispersion forces) and the other to a polar component. In the boxes provided below, draw the structural formula for
each molecule (should be drawn by hand or using a drawing tool - not copy/pasted from a website).
Draw the structural formula for pentane: Draw the structural formula for diethyl ether:
Draw the structural formula for butanone: Draw the structural formula for 2-butanol:
