sublimation

The vapor pressures of 1,2-diphenylethane, p-dichlorobenzene, and 1,3,5-trichlorobenzene are 0.06, 11.2, and 1.4 torr, respectively, at their melting point (52-54 degrees C). Which compound is likely to be sublimed most rapidly at a reduced pressure of 15 torr and a temperature of 40 degrees Celcius?

weight of water

Calculate the weight of water required to steam distill 500mg of bromobenzene at 95 degrees Celsius. the vapor pressure of water at this temperature is 640 torr, bromobenzene is 120 torr.

bromination of trans-cinnamic acid

I recently did an experiment where the addition of bromine to trans-cinnamic acid gives a dibromide with two stereocenters (chiral centers). Thus, there were four stereoisomers possible (see figures on page 136 on attachment). According to the melting points of my product, I ended up with the racemic mixture (2R,3S) and (2S, ...continues
