Question
For each of these compounds, look up their vapor pressure (P°) and their solubility in water (Henry's law constant). Be sure to include appropriate units for these properties. Compare the physical properties of the compounds to their structures and functional groups. For each compound, indicate whether it is a solid, liquid, or gas at 25°C, order them in terms of their vapor pressure and solubility, and briefly explain how their physical properties relate to their structures and functional groups.
Thank you.
3. Vapor pressure and solubility of organic compounds. (review Eby, Ch. 5 or web links about organic compounds). Consider the following set of organic compounds and their melting points (Tm). CAH9 CI Cl C Cl phenol n-butyl 12,3.5-tetra- 1,2,4,5-tetra benzene chlorobenzene chlorobenzene Tm(°C) 43.0-88.0 54.5 140.0 For each of these compounds, look up their vapor pressure (PO) and their solubility in water (Henry's law constant). Be sure to include appropriate units for these properties. Compare the physical properties of the compounds to their structures and functional groups. For each compound, indicate whether it is a solid, liquid, or gas at 25°C, order them in terms of their vapor pressure and solubility, and briefly explain how their physical properties relate to their structures and functional groups.Explanation / Answer
At 250C
Phenol is a solid
n-butyl benzene is a gas
1,2,3,5-tetra-chlorobenzene is a solid
1,2,4,5-tetra-chlorobenzene is a solid
vapor pressure;n-butyl benzene > Phenol > 1,2,3,5-tetra-chlorobenzene > 1,2,4,5-tetra-chlorobenzene
as n-butyl benzene is a gas at 25^0c so it has more vapor pressure
solubility ; phenol( can form hydrogen bonds with water) > 1,2,3,5-tetra-chlorobenzene( more polar) > 1,2,4,5-tetra-chlorobenzene(less polar) >n-butyl benzene (non polar substance)
