Chapter 16, Problem 2Q
Interpretation Introduction

Interpretation:

The procedure for purification of compound that has a vapor pressure of 65torr should be given.

Concept introduction:

Sublimation is a technique in which a solid substance does not melt at an atmospheric process instead of directly undergo change into the gaseous state. Sublimation is used as a purification method for the organic compounds as follows:

  • Vaporize without melting.
  • Vaporize without decomposition.
  • Vapor could be condensed back to solid.

For sublimation to occur successfully, a solid should have a high enough vapor pressure than usual so that it should have a weak intermolecular force.
