Question

High temperature X-ray diffraction is a valuable technique for obtaining ___________

(a) Functional  information on polymers

(b) Structural information on polymorphs

(c) Concentration of polymers

(d) Solubility of polymers

I had been asked this question by my school principal while I was bunking the class.

The origin of the question is Survey of Techniques and their Applications to Solids in chapter Preparative Methods of Solid State Chemistry

Answer 1

The correct answer is (b) Structural information on polymorphs

To explain: High temperature X-ray diffraction is a valuable technique for obtaining the structural information on polymorphs and phases that exist only at high temperatures. It is particularly useful for studying high temperature structures at cannot be preserved to room temperature by quenching.
