Illustrate the phase diagram of acetone and explain your findings.
The boiling points, surface tensions, and viscosities ofwater and several alcohols are as shown below: (a) From ethanol to propanol to n-butanol the boilingpoints, surface tensions, and viscosities all increase. Whatis the reason for this increase?

20. What is the relationship between intermolecular forces (IMFS) and the physical properties of solids and liquids? Using relevant chemical examples and at least one (1) physical property of your choosing, explain the effect of (a) hydrogen bonding; (b) dipole-dipole attractions; and (c) dispersion forces on your chosen physical property. Point form is both accepted and expected for this question. (
