Question

3. The vapor pressures of 1,2-diphenylethane, p-dichlorobenzene, 1,3,5- trichlorobenzene are 0.06, 11.2, and 1.4 torr, respectively, at their melting points (52-54°C). Explain which compound is likely to be sublimed most rapidly at a reduced pressure of 15 torr and a temperature of 40 °C 4 (Comnlete vour catTi

Answer 1

3.

• The compound which will go heavenly quickest will be the one with the most astounding vapor weight
• Subsequently the right answer is (p-dichloro benzene)
• It is due to the sublimation rate of the compound increments with the expansion in vapor weight,
• since the dichloro benzene has the most astounding vapor weight.
• Thus the p-dichloro benzene is suitable for it.
