Explaining Vapor Pressure in Terms of IMFs Given the shown structural formulas for these four compounds, explain their relative vapor pressures in terms of types and extents of IMFs: OH I H₂C-CH₂ ethanol HO OH | | H₂C-CH₂ ethylene glycol Solution CH₂CH₂OH: H-bonding & LDF. CH₂OHCH₂OH: Stronger H-bonding than ethanol (also LDF), and higher MM than H₂O. More viscous than ethanol, thus quite a low P vap. CH3-CH₂-0-CH₂ CH3 and H-O-H diethyl ether water C4H₁0O: Dispersion forces AND dipole-dipole. Diethylether is quite a volatile substance, with quite a high Pvap: vap• H₂O: H-bonding & LDF.
