Which physical property of dihydrogen is wrong?

Which physical property of dihydrogen is wrong?

Raman and Rajan were studying the properties of solids. A solid 'X' showed same physical properties (thermal conductivity and refractive index) in all directions while another solid 'Y' showed differrent physical properties in different directions. Raman classified the solid 'X' as crystalline and solid 'Y' as amorphous. Rajan did not agree with Raman's classification. Answer the following questions What is the natme of the property exhibited by solid 'X'?
