We are being asked to explain the difference in vapor pressure between dichloromethane and carbon tetrachloride.
▪ is the pressure exerted by a vapor in equilibrium with its condensed phase
▪ highly influenced by intermolecular forces between molecules
Intermolecular Forces (IMF) are the attractive forces between 2 molecules.
▪ strongest IMF
▪ deals with the attraction between an ion and a polar compound.
• Hydrogen Bonding
Dichloromethane has a greater solubility in water than in carbon tetrachloride and the two have significantly different vapor pressures at 20°C. See the table below.
Explain the solubility difference between the two compounds in terms of the intermolecular forces present in both molecules.
In terms of the intermolecular forces, explain the difference in vapor pressure between the two compounds.
